GRBFSolve

int GRBFSolve ( GRBmodel *model,
    GRBsvec *b,
    GRBsvec *x )

Computes the solution to the linear system <span>$</span>Bx=b<span>$</span>, where <span>$</span>B<span>$</span> is the current simplex basis matrix, <span>$</span>b<span>$</span> is an input vector, and <span>$</span>x<span>$</span> is the result vector.

Return value:

A non-zero return value indicates that a problem occurred while computing the desired vector. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.

Arguments:

model: The model. Note that the model must have a current optimal basis, as computed by GRBoptimize.

b: The sparse right-hand side vector. It should contain one entry for each non-zero value in the input.

x: The sparse result vector. The user is responsible for allocating the ind and val fields to be large enough to hold as many as one non-zero entry per constraint in the model.
