+
+ Parameters
+ ----------
+ a : array_like
+ The source array.
+ indices : array_like
+ The indices of the values to extract.
+ axis : int, optional
+ The axis over which to select values. By default, the flattened
+ input array is used.
+ out : ndarray, optional
+ If provided, the result will be placed in this array. It should

+ Specifies how out-of-bounds indices will behave.
+
+ * 'raise' -- raise an error (default)
+ * 'wrap' -- wrap around
+ * 'clip' -- clip to the range
+
+ 'clip' mode means that all indices that are too large are replaced

+ Parameters
+ ----------
+ a : array_like
+ Array to be reshaped.
+ newshape : int or tuple of ints
+ The new shape should be compatible with the original shape. If

+def choose(a, choices, out=None, mode='raise'):
+ """
+ Construct an array from an index array and a set of arrays to choose from.
+
+ First of all, if confused or uncertain, definitely look at the Examples -
+ in its full generality, this function is less simple than it might
+ seem from the following code description (below ndi =
+ `numpy.lib.index_tricks`):
+
+ ``np.choose(a,c) == np.array([c[a[I]][I] for I in ndi.ndindex(a.shape)])``.
+
+ But this omits some subtleties. Here is a fully general summary:
+
+ Given an "index" array (`a`) of integers and a sequence of `n` arrays
+ (`choices`), `a` and each choice array are first broadcast, as necessary,
+ to arrays of a common shape; calling these *Ba* and *Bchoices[i], i =
+ 0,...,n-1* we have that, necessarily, ``Ba.shape == Bchoices[i].shape``
+ for each `i`. Then, a new array with shape ``Ba.shape`` is created as
+ follows:
+
+ * if ``mode=raise`` (the default), then, first of all, each element of
+ `a` (and thus `Ba`) must be in the range `[0, n-1]`; now, suppose that
+ `i` (in that range) is the value at the `(j0, j1, ..., jm)` position
+ in `Ba` - then the value at the same position in the new array is the
+ value in `Bchoices[i]` at that same position;
+
+ * if ``mode=wrap``, values in `a` (and thus `Ba`) may be any (signed)
+ integer; modular arithmetic is used to map integers outside the range
+ `[0, n-1]` back into that range; and then the new array is constructed
+ as above;
+
+ * if ``mode=clip``, values in `a` (and thus `Ba`) may be any (signed)
+ integer; negative integers are mapped to 0; values greater than `n-1`
+ are mapped to `n-1`; and then the new array is constructed as above.
+
+ Parameters
+ ----------
+ a : int array
+ This array must contain integers in `[0, n-1]`, where `n` is the number
+ of choices, unless ``mode=wrap`` or ``mode=clip``, in which cases any
+ integers are permissible.
+ choices : sequence of arrays
+ Choice arrays. `a` and all of the choices must be broadcastable to the
+ same shape. If `choices` is itself an array (not recommended), then
+ its outermost dimension (i.e., the one corresponding to
+ ``choices.shape[0]``) is taken as defining the "sequence".
+ out : array, optional
+ If provided, the result will be inserted into this array. It should
+ be of the appropriate shape and dtype.
+ mode : {'raise' (default), 'wrap', 'clip'}, optional
+ Specifies how indices outside `[0, n-1]` will be treated:
+
+ * 'raise' : an exception is raised
+ * 'wrap' : value becomes value mod `n`
+ * 'clip' : values < 0 are mapped to 0, values > n-1 are mapped to n-1
+
+ Returns
+ -------
+ merged_array : array
+ The merged result.
+
+ Raises
+ ------
+ ValueError: shape mismatch
+ If `a` and each choice array are not all broadcastable to the same
+ shape.
+
+ See Also
+ --------
+ ndarray.choose : equivalent method
+
+ Notes
+ -----
+ To reduce the chance of misinterpretation, even though the following
+ "abuse" is nominally supported, `choices` should neither be, nor be
+ thought of as, a single array, i.e., the outermost sequence-like container
+ should be either a list or a tuple.
+
+ Examples
+ --------
+
+ >>> choices = [[0, 1, 2, 3], [10, 11, 12, 13],
+ ... [20, 21, 22, 23], [30, 31, 32, 33]]
+ >>> np.choose([2, 3, 1, 0], choices
+ ... # the first element of the result will be the first element of the
+ ... # third (2+1) "array" in choices, namely, 20; the second element
+ ... # will be the second element of the fourth (3+1) choice array, i.e.,
+ ... # 31, etc.
+ ... )
+ array([20, 31, 12, 3])
+ >>> np.choose([2, 4, 1, 0], choices, mode='clip') # 4 goes to 3 (4-1)
+ array([20, 31, 12, 3])
+ >>> # because there are 4 choice arrays
+ >>> np.choose([2, 4, 1, 0], choices, mode='wrap') # 4 goes to (4 mod 4)
+ array([20, 1, 12, 3])
+ >>> # i.e., 0
+
+ A couple examples illustrating how choose broadcasts:
+
+ >>> a = [[1, 0, 1], [0, 1, 0], [1, 0, 1]]
+ >>> choices = [-10, 10]
+ >>> np.choose(a, choices)

+ Axis along which to sort. If None, the array is flattened before
+ sorting. The default is -1, which sorts along the last axis.
+ kind : {'quicksort', 'mergesort', 'heapsort'}, optional
+ Sorting algorithm. Default is 'quicksort'.
+ order : list, optional
+ When `a` is a structured array, this argument specifies which fields
+ to compare first, second, and so on. This list does not need to
+ include all of the fields.
+
+ Returns
+ -------
+ sorted_array : ndarray
+ Array of the same type and shape as `a`.
+
+ See Also
+ --------
+ ndarray.sort : Method to sort an array in-place.
+ argsort : Indirect sort.
+ lexsort : Indirect stable sort on multiple keys.
+ searchsorted : Find elements in a sorted array.
+
+ Notes
+ -----
+ The various sorting algorithms are characterized by their average speed,
+ worst case performance, work space size, and whether they are stable. A
+ stable sort keeps items with the same key in the same relative
+ order. The three available algorithms have the following
+ properties:
+
+ =========== ======= ============= ============ =======
+ kind speed worst case work space stable
+ =========== ======= ============= ============ =======
+ 'quicksort' 1 O(n^2) 0 no
+ 'mergesort' 2 O(n*log(n)) ~n/2 yes
+ 'heapsort' 3 O(n*log(n)) 0 no
+ =========== ======= ============= ============ =======
+
+ All the sort algorithms make temporary copies of the data when
+ sorting along any but the last axis. Consequently, sorting along
+ the last axis is faster and uses less space than sorting along
+ any other axis.
+
+ The sort order for complex numbers is lexicographic. If both the real
+ and imaginary parts are non-nan then the order is determined by the
+ real parts except when they are equal, in which case the order is
+ determined by the imaginary parts.
+
+ Previous to numpy 1.4.0 sorting real and complex arrays containing nan
+ values led to undefined behaviour. In numpy versions >= 1.4.0 nan
+ values are sorted to the end. The extended sort order is:
+
+ * Real: [R, nan]
+ * Complex: [R + Rj, R + nanj, nan + Rj, nan + nanj]
+
+ where R is a non-nan real value. Complex values with the same nan
+ placements are sorted according to the non-nan part if it exists.
+ Non-nan values are sorted as before.
+
+ Examples
+ --------
+ >>> a = np.array([[1,4],[3,1]])
+ >>> np.sort(a) # sort along the last axis
+ array([[1, 4],
+ [1, 3]])
+ >>> np.sort(a, axis=None) # sort the flattened array
+ array([1, 1, 3, 4])
+ >>> np.sort(a, axis=0) # sort along the first axis
+ array([[1, 1],
+ [3, 4]])
+
+ Use the `order` keyword to specify a field to use when sorting a
+ structured array:
+
+ >>> dtype = [('name', 'S10'), ('height', float), ('age', int)]
+ >>> values = [('Arthur', 1.8, 41), ('Lancelot', 1.9, 38),
+ ... ('Galahad', 1.7, 38)]

+ Notes
+ -----
+ The standard deviation is the square root of the average of the squared
+ deviations from the mean, i.e., ``std = sqrt(mean(abs(x - x.mean())**2))``.
+
+ The average squared deviation is normally calculated as ``x.sum() / N``, where
+ ``N = len(x)``. If, however, `ddof` is specified, the divisor ``N - ddof``
+ is used instead. In standard statistical practice, ``ddof=1`` provides an
+ unbiased estimator of the variance of the infinite population. ``ddof=0``
+ provides a maximum likelihood estimate of the variance for normally
+ distributed variables. The standard deviation computed in this function
+ is the square root of the estimated variance, so even with ``ddof=1``, it
+ will not be an unbiased estimate of the standard deviation per se.
+
+ Note that, for complex numbers, `std` takes the absolute
+ value before squaring, so that the result is always real and nonnegative.
+
+ For floating-point input, the *std* is computed using the same
+ precision the input has. Depending on the input data, this can cause
+ the results to be inaccurate, especially for float32 (see example below).
+ Specifying a higher-accuracy accumulator using the `dtype` keyword can
+ alleviate this issue.
+
+ Examples
+ --------
+ >>> a = np.array([[1, 2], [3, 4]])
