MATLAB: Indexing entry of a matrix result

Question

A is an MxN matrix. To get the number of columns of A I can do the following:

s = size(A);
ncol = s(2);

How can I construct a direct expression avoiding the intermediary variable s?

Answer 1

 [nRows, nCols] = size( A ) ;

if you don't need nRows:

 [~, nCols] = size( A ) ;
