COLS

Number of columns (i.e. variables) in the matrix.

Integer

If the matrix is in a presolved state, this attribute returns the number of columns in the presolved matrix. If you require the value for the original matrix then use the ORIGINALCOLS attribute instead. The PRESOLVESTATE attribute can be used to test if the matrix is presolved or not. See also Working with Presolve.
