Trigonometric functions sin(x[, out]) Trigonometric sine, element-wise. cos(x[, out]) Cosine element-wise. tan(x[, out]) Compute tangent element-wise. arcsin(x[, out]) Inverse sine, element-wise. arccos(x[, out]) Trigonometric inverse cosine, element-wise. arctan(x[, out]) Trigonometric inverse tangent, element-wise. hypot(x1, x2[, out]) Given the ?legs? of a right triangle, return its hypotenuse. arctan2(x1, x2[, out]) Element-wise arc tangent of x1/x2 choosing the quadrant correctly

masked_array.mask Mask

MaskedArray.__xor__ x.__xor__(y) <==> x^y

MaskedArray.__sub__(other) [source] Subtract other from self, and return a new masked array.

MaskedArray.__str__() [source] String representation.

MaskedArray.__truediv__(other) [source] Divide other into self, and return a new masked array.

MaskedArray.__setstate__(state) [source] Restore the internal state of the masked array, for pickling purposes. state is typically the output of the __getstate__ output, and is a 5-tuple: class name a tuple giving the shape of the data a typecode for the data a binary string for the data a binary string for the mask.

MaskedArray.__setslice__(i, j, value) [source] x.__setslice__(i, j, value) <==> x[i:j]=value Set the slice (i,j) of a to value. If value is masked, mask those locations.

MaskedArray.__setitem__(indx, value) [source] x.__setitem__(i, y) <==> x[i]=y Set item described by index. If value is masked, masks those locations.

MaskedArray.__setmask__(mask, copy=False) [source] Set the mask.
