numpy.ma.cumprod()
numpy.ma.cumprod
-
numpy.ma.cumprod(self, axis=None, dtype=None, out=None) = -
Return the cumulative product of the elements along the given axis. The cumulative product is taken over the flattened array by default, otherwise over the specified 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.
Parameters: axis : {None, -1, int}, optional
Axis along which the product is computed. The default (
axis= None) is to compute over the flattened array.dtyp
