# QCELEMS

Description | Number of quadratic row coefficients in the matrix.
Type | Integer
Topic areas | Problem Information, Quadratic
Note | If the matrix is in a presolved state, this attribute returns the number of quadratic row coefficients in the presolved matrix. If you require the value for the original matrix then use the ORIGINALQCELEMS attribute instead. The PRESOLVESTATE can be used to test if the matrix is presolved or not. See also Working with Presolve.
