Matlab not recognize optimproblem and optimvar in Optimization problem

Hello all. I am writing an optimization problem using Matlab. However, when I run the code, it says undefined function or variable 'optimproblem'and 'optvar'. I thought this function is already set up in Matlab. What do I need to do to for Matlab to recognize these?

Thank you so much for your help!!!

We need to see copy/pastes of code and error messages. We also need to know what version of Matlab you are running.

optimproblem and optimvar were introduced in R2017b. If you have an earlier version of MATLAB, these functions are not available.
