Hi, 

I have a question about cplexqcp in matlab. The problem that I am trying to solve consists of several sparse quadratic constraints. Is there a way to avoid defining "cell arrays" or "struct vectors" for using cplexqcp?

For example, can I stack all of the matrices Q{1}, Q{2}, ... Q{m}, in a huge "n^2 by n" sparse matrix and give it to cplexqcp?

In my problem m = 53000 and it takes a few minutes to reformulate the constraints in "cell array" or "struct vector" formats.

Thank you in advance for your help.

Would it be an option to use the class API instead of the toolbox API? In the class API you can add quadratic constraints one by one.
