exportprob

Purpose

Export a quadratic problem to a file.

Synopsis

procedure exportprob(options:integer, filename:string, obj:qexp.

Arguments

options	File format options: EP_MIN  LP format, minimization EP_MAX  LP format, maximization EP_MPS  MPS format EP_STRIP  Use scrambled names
filename	Name of the output file; if empty, output printed to standard output (screen)
obj	Objective function (quadratic expression)

Example

The following example prints the problem to screen using the default format, and then exports the problem in LP-format to the file prob1.lp maximizing constraint Profit:

uses "mmquad"
declarations
 Profit:qexp
end-declarations
 ...
exportprob(0, "", Profit)
exportprob(EP_MAX, "prob1", Profit) 

Further information

This procedure overloads the exportprob subroutine of Mosel to handle quadratic objective functions. It exports the current problem to a file, or if no file name is given (empty string ""), prints it on screen. If the given filename has no extension, Mosel appends .lp to it for LP format files and .mat for MPS format.
