Error: Unable to locate 'mexopts.bat'

I am trying to simulate the file in the following link-

http://www.mathworks.com/matlabcentral/fileexchange/35736-solar-and-mppt

But i am getting a error message "Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds. Use 'mex -setup' to select a supported compiler." Please somebody suggest some solution of it.

I would suggest you follow the advice of the error message! Type this at the command line:

mex -setup

This a clear and clean answer, nevertheless, I'm amused.

thank you so much..it works... after entering mex -setup, you just need give yes to 1 or 2 qns and you are done.._Unable to locate mexopts.bat_ issue is resolved.

You need to install a supported compiler if you don't have one already. Look at the last column on this page against your MATLAB version: http://www.mathworks.com/support/sysreq/previous_releases.html

I got the same question，"Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds.

And I try to enter 'mex -setup' the output is :

Unknown encoding 'cp65001' at D:\Program Files\MATLAB\R2010b\bin\/mexutils.pm line 154

??? Error using ==> mex at 208

Unable to complete successfully.

PS: my version is 2010b. And actually, I've already installed the compiler, which I can see on 2020a
