MaskedArray.cumprod(self, axis=None, dtype=None, out=None)
Return the cumulative product of the array elements over the given axis.
Masked values are set to 1 internally during the computation. However, their position is saved, and the result will be masked at the same locations.
numpy.cumprod for full documentation.
The mask is lost if
out is not a valid MaskedArray !
Arithmetic is modular when using integer types, and no error is raised on overflow.
