First，I finisihed the installation cvx in matlab by downloading the cvx package including the gurobi in “http://cvxr.com/”. Then I use “cvx_grbgetkey” to finish the configuration of Gurobi. Finally, the cvx can find the Gurobi solver successfully. But it displays the error “Model.quadcon must be a struct array with fields q, and rhs error in CVX”, I know that there is mismatching problem between the Cvx version and Gurobi version possibly through searching online. Therefore, I try to download Gurobi 9.0.0 package individually and then configure as before.
Now I run “cvx_grbgetkey ****”,it displays
cvx_grbgetkey 4488f556-71f5-11ec-a97b-0242ac120003
