XSLPevaluatecoef

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.
ColIndex 
Integer index of the column.
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).
