buildqtls


Purpose
Generate data required for loading a quadratic expression.
Synopsis
int buildqtls(XPRMcontext ctx, void *nlctx, XPRMnlctr qctr, int onlyqterms, int *nbterm, XPRMnlqterm *qtls, double *cstt);
Arguments
ctx 
Mosel's execution context
nlctx 
mmnl execution context
qctr 
Quadratric constraint or objective to process
onlyqterms 
Ignore linear terms
nbterm 
Reference where the number of qterms is returned
qtls 
Reference where the list of qterms is returned
cstt 
Reference where the constant terms is returned
Return value
0 if the expression is constant, 1 for a linear, 2 for a quadratic, 4 for a nonlinear expression and -1 in case of error
Further information
1. This function computes the list of quadratic terms of a quadratic expression. If the option onlyqterms is not specified then linear terms are also included in the list (the second variable reference of a linear term is NULL).
2. The list qtls is allocated by the routine: each call to buildqtls must be followed by a call to freeqtls in order to release the allocated memory.
