problem.evaluatecoef
problem.evaluatecoef |
Purpose
Evaluate a coefficient using the current values of the variables
Synopsis
value = problem.evaluatecoef(rowindex, colindex)
Arguments
|
rowindex
|
Row (i.e.
xpress.constraint object, index, or name).
|
|
colindex
|
Column (i.e.
xpress.var object, index, or name).
|
|
value
|
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.
p.chgvar(5, None, None, None, None,
None, None, 1.42, None, None, None,
None)
value = p.evaluatecoef(2, 3)
Further information
The values of the variables are obtained from the solution, or from the
Value setting of an SLP variable (see
problem.chgvar and
problem.getvar).
