Source 
pub unsafe extern "C" fn SCIPchgNlRowLinearCoef(

Expand description

changes linear coefficient of a variables in a nonlinear row

Setting the coefficient to 0.0 means that it is removed from the row. The variable does not need to exists before.

@return \ref SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See \ref SCIP_Retcode “SCIP_RETCODE” for a complete list of error codes.

@pre This method can be called if SCIP is in one of the following stages: - \ref SCIP_STAGE_PRESOLVED - \ref SCIP_STAGE_INITSOLVE - \ref SCIP_STAGE_SOLVING
