Synopsis
procedure writeprob(fname:string, options:string)
procedure writeprob(fname:string, options:string, fnamed:string)
Arguments

Extended file name for the matrix
|
|
options
|
String of format options (default: full precision)

|
fnamed

Example
Load the current problem into the Optimizer and save it to an MPS file
"mypb.mps" in hexadecimal format ('x') and to the file
"mypb.lp" in LP format ('l') using scrambled names ('s'):
loadprob(myobj)
setparam("xprs_objsense",1) ! for 'minimize'
writeprob("mypb.mps","x")
writeprob("mypb.lp","ls")
Further information
This procedure writes the current problem held in the Optimizer to a file by calling the Optimizer function
XPRSwriteprob and
XPRSwritedirs if a file name for the directives is also specified. Note that the matrix written by this procedure may be different from the one produced by
exportprob since it may include the effects of presolve or cuts generated by the Optimizer. For more detail on the options and behavior of this procedure, refer to the
Xpress Optimizer Reference Manual.
