Warnings and incorrect results with latest version in MATLAB

Hello

I am new to gurobi, cvx and matlab. I installed gurobi and added it to matlab, then added academic license for gurobi. Then I proceeded to install cvx and get academic license for that as well so I can use it with gurobi. However during cvx installation, I get the following warnings:

"

done!

 

When using gurobi_2 and gurobi_3, I cannot solve any problems, the optimal value is always 0 and it tells me status is solved and optimal value is reached, but gurobi (7.5) solves them without any warnings or errors and gives a reasonable solution.

Please let me know if I can fix this because I want to take advantage of latest gurobi version.

 

Thank you in advance.
