exportProb Method

Same as exportProb(BCLconstant.XPRB_LP, null);

Print problem matrix to a file. This method prints the matrix to a file with an extended LP or extended MPS format. Provided that no extension is given by the user LP files receive the extension .lp. MPS files always receive the extension .mat. 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. The precision used by BCL for printing real numbers can be changed with setRealFmt(string) 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 XPRSprob.writeProb, preceded by a call to loadMat().
