# numpy.ma.masked_array.cumprod

`masked_array.``cumprod`(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.

  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.
