XPRBexportprob
XPRBexportprob |
Purpose
Synopsis
int XPRBexportprob(XPRBprob prob, int format, char *filename);
Arguments
|
prob
|
Reference to a problem.
|
||||
|
format
|
The matrix output file format, which must be one of:
|
||||
|
filename
|
Name of the output file, without extension.
|
Return value
0 if function executed successfully, 1 otherwise.
Example
XPRBprob expl2;
expl2 = XPRBnewprob("example2");
XPRBexportprob(expl2, XPRB_MPS, "ex2");
This prints the problem in MPS format to the file
ex2.mps.
Further information
1. This function prints the matrix to a file with an extended LP or extended MPS format. LP files receive the extension
.lp and MPS files receive the extension
.mps. This function is not available in the
student version.
2. When exporting matrices semi-continuous and semi-continuous integer variables are preprocessed: if a lower bound value greater than 0 is given, then the variable is treated like a continuous (resp. integer) variable.
3. The precision used by BCL for printing real numbers can be changed with
XPRBsetrealfmt to obtain more accurate output for very large or very small numbers. For full precision matrix output the user is advised to switch to the Optimizer function
XPRSwriteprob, preceded by a call to
XPRBloadmat (see Appendix
Using BCL with the Optimizer library for further detail).
