firstnonsingleton Finds first dimension which is not 1

## Syntax

    [dim]=firstnonsingleton(A[,opt])

## Arguments

dim

  first dimension of A which is not 1

A

  a variable of any Scilab data type

opt

  a character string giving the type of output we want

  "num"

    returned value is a numerical value

  "str"

    returned value is a character string if possible ("r" instead of 1 and "c" instead of 2)

## Description

This function is used by `mfile2sci` to emulate Matlab behavior under Scilab, particularly for functions which treat the values along the first non-singleton dimension of A in Matlab while in Scilab they treat all values of A.

## Examples

    A = [1 2 3;4 5 6];
    // Scilab max
    M = max(A)
    // Matlab max emulation
    M = max(A,firstnonsingleton(A))
