numpy.ma.masked_array.cumprod

method

masked_array.cumprod(self, axis=None, dtype=None, out=None) [source]

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.

Refer to numpy.cumprod for full documentation.

Notes

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.
