bbsolvemem Estimate memory usage for solving a linear system. MEM=bbsolvemem(BB,OPT) estimates the memory (in megabytes) used internally by bbpresolve. It has exactly the same syntax as bbsolveopt. While bbsolveopt usually generates a good set of options (please file a bug report otherwise), it is generally conservative and may use more memory than you have. bbsolvemem can check if the computation is feasible on your computer before your hardrive crashes under the weight of the virtual memory system.
