Matrix related functions

The functions presented in this section are used to obtain the matrix representation of the current problem (LP/MIP) from Mosel and to inform Mosel about the result of a solution process that has been used on the provided matrix. The data structure used to represent a matrix (XPRMmatrix) is not described in this document, the reader is referred to the header file mosel_sl.h for further details. The structure XPRMmipsolver is documented with the function loadmat.
