firstnonsingleton
=================

Finds first dimension which is not 1



Calling Sequence
~~~~~~~~~~~~~~~~


::

    [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))
