[Numpy-discussion] slight MapIter change

[Sebastian Berg]

Hey,

(this is only interesting if you know what MapIter and actually use it)

In case anyone already uses the newly exposed mapiter (it was never
released yet). There is a tiny change, which only affects indexes that
start with np.newaxis but otherwise just simplifies a tiny bit. The old
block for swapping axes should be changed like this:

     if ((mit->subspace != NULL) && (mit->consec)) {
-        if (mit->iteraxes[0] > 0) {
-            PyArray_MapIterSwapAxes(mit, (PyArrayObject **)&arr, 0);
-            if (arr == NULL) {
-                return -1;
-            }
+        PyArray_MapIterSwapAxes(mit, (PyArrayObject **)&arr, 0);
+        if (arr == NULL) {
+            return -1;
         }
     }

Regards,

Sebastian
