problem.getqrowqmatrixtriplets |
Purpose
Returns the nonzeros in a quadratic constraint coefficients matrix as triplets (index pairs with coefficients). To achieve maximum efficiency,
getqrowqmatrixtriplets returns the lower triangular part of this matrix only.
Synopsis
problem.getqrowqmatrixtriplets (irow, mqcol1, mqcol2, dqe)
Arguments
|
irow
|
Index of the row for which the quadratic coefficients are to be returned.
|
|
nqelem
|
Argument used to return the number of quadratic coefficients in the row.
|
|
mqcol1
|
First index in the triplets. May be
None if not required.
|
|
mqcol2
|
Second index in the triplets. May be
None if not required.
|
|
dqe
|
Coefficients in the triplets. May be
None if not required.
|
Further information
If a row index of
-1 is used, the function returns the quadratic coefficients for the objective function.
