>From the numarray manual 18.5.1
The result of a unary operation will be masked whenever the original
operand was masked.... The following functions have their standard
absolute, ...., sin, ...
I would have expected this to work
import numarray as nx
import numarray.ma as ma
t = nx.arange(0.0, 2.0, 0.01)
tm = ma.masked_outside(t, .2, 1.2)
s = nx.sin(tm)
but instead I get
/usr/lib/python2.4/site-packages/numarray/ma/MA.py in __array__(self, t)
673 if self._mask is not None:
674 if Numeric.any(self._mask):
--> 675 raise MAError, \
676 """Cannot automatically convert masked array to Numeric because data
677 is masked in one or more locations.
MAError: Cannot automatically convert masked array to Numeric because data
is masked in one or more locations.
I see the same with Numeric and MA
Am I misreading this? Does "have their standard meaning" mean that MA
is not supported?
