Matlab cumprod emulation function
Matlab and Scilab cumprod
behave differently in some particular cases:
When used with one input (cumprod(A)
), Matlab cumprod
treats the values along the first non-singleton dimension of A as vectors while
Scilab cumprod
treats all A values.
When used with two inputs (cumprod(A,dim)
), Matlab tolerates dim
to be greater than the number of dimensions of A while Scilab returns an error message in this case.
The function R = mtlb_cumprod(A[,dim])
is used by
mfile2sci
to replace cumprod(A[,dim])
when it was not
possible to know what were the inputs while porting Matlab code to Scilab. This function will
determine the correct semantic at run time. If you want to have a
more efficient code it is possible to replace mtlb_cumprod
calls:
If dim
is less equal to the number of dimensions of A
R = mtlb_cumprod(A,dim)
may be replaced by R = cumprod(A,dim)
If dim
is greater than then number of dimensions of A
R = mtlb_cumprod(A,dim)
may be replaced by R = A
.
