prod (Matlab function) Product of array elements

## Matlab/Scilab equivalent

Matlab | Scilab
    prod
    prod

## Particular cases

M=prod(A)

  Scilab prod(A) returns the product of all components of A. So, if A is a vector, then Scilab and Matlab work in the same way. If A is a matrix, Scilab prod(A) gives the product of all elements of A but Matlab returns the product of each column. Finally, if A is a multidimensional array, Matlab works on the first non-singleton dimension of A what Scilab does not. So, to be sure to find a Scilab equivalent for Matlab call to prod it is better to precise dimension on which to work.

M=prod(A,dim)

  In Scilab dim=1 is equivalent to dim="r" and dim=2 is equivalent to dim="c". In Matlab, dim can be greater than the number of dimension of A (in this case, M=A), in Scilab you will get an error message.

## Examples

Matlab | Scilab
    A = [1,2,3;4,5,6]
    M = prod(A)
    M = [4,10,18]
    M = prod(A,1)
    M = [4,10,18]
    A = [1,2,3;4,5,6]
    M = prod(A)
    M = 720
    M = prod(A,"r")
    M = [4,10,18]
