Hi,
I am facing an issue with CVXv2.2 and external installation of gurobi (academic licensed).
I have Gurobi installed and added to MATLAB path. However, on running the following commands removes gurobi from my path`
cvx_solver Gurobi_2
cvx_save_prefs
cvx_setup
Why is that?
There was some path clobbering in earlier builds of CVX 2.2, but I think they may be resolved in the current build (1148), or at least don’t manifest in as many cases… So if you’re not using build 1148, try installing it.
Thank you for the quick response. I am using the current build 1148.
