There is a single array with both - columns then rows and then normally two arrays pointing to rows and columns.

The single array is the owner of memory

Function Documentation

void ClpSimplexUnitTest ( const std::string &  mpsDir)

A function that tests the methods in the ClpSimplex class.

The only reason for it not to be a member method is that this way it doesn't have to be compiled into the library. And that's a gain, because the library should be compiled with optimization on, but this method should be compiled with debugging.

It also does some testing of ClpFactorization class
