It works, thanks.

It's already on, it fills the user/pass for me, and I need to press the button. But again, I prefer not to go through an extra login page each time: - get to the thread page, press sign in - wait f...

The C interface supports CSC sparse rep, which should do the trick (c/c++ are all the same).  About a working example. I have a 3M X 30M matrix, with ~10 nnz in a row. If you use the addTerms in a ...

I tried both chrome and firefox. When I enter the thread url, it doesn't recognize me in both. If I want to leave a comment, then it suggests that I log in. I click the login: firefox: it refreshes...

Using addTerms instead of += to add one term at the time cut the time by half, but not in an order of magnitude (e.g. from 2sec to 1sec, instead of 0.02sec). addTerms of all eq terms didn't make mu...

I naively thought that it's just a matter of solving a linear system of equalities, which usually takes under a second rather than a minute (using packages such mldivide, pardiso, umfpack). However...

I missed that, thanks.

The mechanism for adding constraints is incredibly slow. Summing the matrix coeff takes 0.02sec. Gurobi adding constraints takes 7sec.  Gurobi optimizing the model takes 5sec. GRBEnv genv;GRBModel ...

dense_optimize() in dense_c++.cpp seems close enough and requires only minor adjustments, thanks.

Okay, thanks.
