CPLEX Callbacks in Matlab

This page is part of the CPLEX Manual. See CPLEX.

Fifteen of the CPLEX callbacks are defined as Matlab m-files. A logical vector defines the callbacks to be used in CPLEX. This vector is named callback and is one of the input variables to the level 1 interface routine cplex.m (Appendix A). If the ith entry of the logical vector callback is set, the corresponding callback is defined.

The callback calls the m-file specified in #Table: Matlab Callback routines. The user can edit this m-file directly, or make a new copy. It is important that a new copy is placed in a directory that is searched before the cplex directory when Matlab goes through the Matlab path.
