Computes the solution to the linear system
, where
is the current simplex basis matrix,
is an input vector, and
is the result vector.
Return value:
A non-zero return value indicates that a problem occurred while computing the desired vector. Refer to theError Codetable for a list of possible return values. Details on the error can be obtained by callingGRBgeterrormsg.
Arguments:
model: The model. Note that the model must have a current optimal basis, as computed byGRBoptimize.
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 theindandvalfields to be large enough to hold as many as one non-zero entry per constraint in the model.
