XPRSgetlpsolval

Purpose

Used to obtain a single LP solution value following optimization.

Synopsis

int XPRS_CC XPRSgetlpsolval(XPRSprob prob, int col, int row, double *x, double *slack, double *dual, double *dj);

Arguments

prob	The current problem.
col	Column index of the variable for which to return the solution value.
row	Row index of the constraint for which to return the solution value.
x	Double pointer where the value of the primal variable will be returned. May be NULL if not required.
slack	Double pointer where the value of the slack variable will be returned. May be NULL if not required.
dual	Double pointer where the value of the dual variable ( c_B^TB^-1) will be returned. May be NULL if not required.
dj	Double pointer where the reduced cost for the variable ( c^T-c_B^TB^-1A) will be returned. May be NULL if not required.

Further information

This function is currently not supported if the problem is in a presolved state.
