Why am I getting a quadprog error Unexpected Standard exception from MEX file. What() is:bad allocation?

19 views (last 30 days)
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.
