GUROBI Using the Matlab Interface
|
|
This page is part of the GUROBI Manual. See GUROBI. |
The two main routines in the two-layer design of the interface are shown in <xr id="tab:interfaceRoutines"/>. Page and section references are given to detailed descriptions on how to use the routines. Users not using the TOMLAB Prob format can skip reading about the routine gurobiTL. A more advanced user, only has to read about how to call the level 1 interface routine gurobi.m.
<figtable id="tab:interfaceRoutines">
| Function | Description |
|---|---|
| gurobi | The layer one Matlab interface routine, calls the MEX-file interface grbmex.dll |
| gurobiTL | The layer two TOMLAB interface routine that calls gurobi.m. Con- verts the input P rob format before calling gurobi.m and converts back to the output Result structure.
</figtable> The GUROBI control parameters (GUROBI Appendix C in this manual), are all possible to set from Matlab. They could be set as input to the interface routine gurobi. The user sets fields in a structure called grbControl, where the subfield names are the same as the names of the control variables (not case-sensitive). The following example shows how to set the values for one integer variable ITERLIM, one double variable INTFEASTOL, and one character variable valued variable WRITEPARAMS. grbControl.ITERATIONLIMIT = 50; % Setting maximal number of simplex iterations grbControl.INTFEASTOL = 1E-5; % Integer feasibility tolerance grbControl.WRITEPARAMS = 'myPar.txt'; % File name for parameter write |
