why I can't work with the optimization Toolbox?

When I run this code: options = optimoptions('patternsearch');, Matlab keeps displaying the error below:

'optimoptions' requires Optimization Toolbox.

I use my university lisence and I don't have access to any account related to it but when I check Add-ons or type ver it shows that both Global optimization toolbox (Version 4.4 ) and optimization toolbox (Version 9) are installed. (Matlab is version R2020b)

I don't know how to fix this problem. I would be grateful if you could help me out with it.

ver tells you, if the toolbox is installed. This shows, if you have an active license for this toolbox:

license('test', 'Optimization_Toolbox')

If this replies 0, try:

[status, msg] = license('checkout', 'Optimization_Toolbox')

Thank you for you help.

it displays:

'License checkout failed.

License Manager Error -5

Cannot find a license for Optimization_Toolbox.

Troubleshoot this issue by visiting:

https://www.mathworks.com/support/lme/R2020b/5

Diagnostic Information:

Feature: Optimization_Toolbox

License path: C:\Users\rahmatna\AppData\Roaming\MathWorks\MATLAB\R2020b_licenses;C:\Program Files\MATLAB\R2020b\licenses\license.dat;C:\Program Files\MATLAB\R2020b\licenses\network.lic

Licensing error: -5,147.'

So although it shows that this toolbox is installed, I can't use it.

what can I do now?

Thank you again

Ask your university to provide the license
