XSLPevaluatecoef

---

Purpose

Evaluate a coefficient using the current values of the variables

Synopsis

int XPRS_CC XSLPevaluatecoef(XSLPprob Prob, int RowIndex, int ColIndex, double *dValue);

Arguments

Prob	The current SLP problem.
RowIndex	Integer index of the row. This respects the setting of XPRS_CSTYLE.
ColIndex	Integer index of the column. This respects the setting of XPRS_CSTYLE.
Value	Address of a double precision value to receive the result of the calculation.

Example

The following example sets the value of column 5 to 1.42 and then calculates the coefficient in row 2, column 3. If the coefficient depends on column 5, then a value of 1.42 will be used in the calculation.

double Value, dValue;

Value = 1.42;
XSLPchgvar(Prob, 5, NULL, NULL, NULL, NULL, 
           NULL, NULL, &Value, NULL, NULL, NULL, 
           NULL);
XSLPevaluatecoef(Prob, 2, 3, &dValue);

Further information

The values of the variables are obtained from the solution, or from the Value setting of an SLP variable (see XSLPchgvar and XSLPgetvar).
