I was solving some problems using quadprog but I observed that for larger inputs I run into the following message: error in quadprog

Unexpected Standard exception from MEX file.

What() is:bad allocation

The same code is able to run on other computers, but takes an extremely long time.

This error is due to a memory issue.

Making all matrices sparse before calling quadprog reduces the computing time and also eliminates the error.
