Deprecated in Analytica 4.3. Renamed to OptWrite.
LpWrite(lp,filename, format)
Writes a linear program definition to a file. Three textual formats are supported, which can be selected using the optional «format» parameter:
- "LP" (default)
- "MPS"
- "LPFML"
The «filename» is interpreted relative to the CurrentDataDirectory.
When debugging an LP, to figure out if you defined your constraints and decision variables as intended, it can sometimes be helpful to view the file written by LpWrite in a text editor.
The file written by LpWrite can be read back in as an LP using LpRead.
LpWrite is not able to write textual specifications for quadratic (QP or QCP) or non-linear (NLP) problems.
