Matlab prod emulation function
Matlab and Scilab prod
behave differently in some particular cases:
When called with one input: Matlab prod
treats the values along the first
non-singleton dimension of input while Scilab prod
threats all values of input.
When called with two inputs: Matlab prod
can be used with second input giving
a non-existing dimension of first input while Scilab prod
returns an error message.
The function mtlb_prod(A[,dim])
is used by
mfile2sci
to replace prod(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_prod
calls:
When called with one input, if A
is an empty matrix, a scalar or a vector,
mtlb_prod(A)
may be replaced by prod(A)
When called with one input, if A
is a not-empty matrix,
mtlb_prod(A)
may be replaced by prod(A,1)
When called with one input, if A
is a multidimensional array,
mtlb_prod(A)
may be replaced by prod(A,firstnonsingleton(A))
When called with two inputs, if dim
is lesser than the number of dimensions of A
mtlb_prod(A,dim)
may be replaced by prod(A,dim)
