ismember (Matlab function) Data sets membership comparison

## Matlab/Scilab equivalent

Matlab | Scilab
    // a)
    AinB = ismember(A, B)

    // b)
    [AinB, loc] = ismember(A, B)
    // c)
    [rAinB, loc] = ismember(A, B, 'rows')
    // a)
    mA = members(A, B);
    AinB = bool2s(mA~=0)
    // b)
    [mA, loc] = members(A, B)
    // c)
    [rmA, loc] = members(A, B, "rows");
    rAinB = bool2s(rmA~=0)

## Description

In addition, Scilab provides the number of occurrences, can provide the locations of last occurrences instead of the first ones, can process A and B column-wise, and can ignore the order of elements in each row/column to be detected (detection of permutations).
