NCOL Function

NCOL( matrix ) ;

The NCOl function returns the number of columns in its matrix argument. If the matrix has not been given a value, the NCOL function returns a value of 0.

For example, following statements display the number of columns of the matrix m:

m = {1 2 3, 4 5 6, 3 2 1, 4 3 2, 5 4 3};
p = ncol(m);
print p;
