The error invalid use of operater came about because you were using the \ operator in a non-prescribed manner (in a way different than the way MATLAB defines the usage of the \ operator). If you want to do more than just the simple plot command, then I would echo @Rik's advice to...
Invalid use of operator. 1 Comment Sarvesh Kale on 9 Feb 2023 Open in MATLAB Online The error is in the following line ThemeCopy p=size (ParamName,1); for j=1:p; param(j,:)=unifrnd(initDisPar(j,1),initDisPar(j,2),1,n); ParamResul(j,:)=[ParamName(j,:) 'Resul']...

Or write each command on separate lines (like you do later in the code). Note that you will see other errors as your code tries to reference the variable

This is a very poor choice for a user-defined function name since that is the name of the MATLAB operator ==. So my guess is you are shadowing the MATLAB == operator with your eq function. Try picking a different name for your eq function, e.g. "myequation" or something else...

Please note that I had to use Mosek solver in order to define the binary variable (alp). Please also note when we change the times (.*) operator with plus (+) in the objective, the CVX can solve the problem. MATLAB code: clc ...
