writeprob

Purpose
Write the current problem to a file.
Synopsis
procedure writeprob(fname:string, options:string)
procedure writeprob(fname:string, options:string, fnamed:string)
Arguments
fname 
Extended file name for the matrix
options 
String of format options (default: full precision)
fnamed 
Extended file name for the directives
Example
Load the current problem into the Optimizer and save it to an MPS file "mypb.mps" 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","")
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.
