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).
