Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds. Use 'mex -setup' to select a supported compiler.

THANKS, BUT STILL I AM NOT SURE WHICH COMPILER TO USE FROM LISTED ONES ?

Deepak: You may choose any of the supported compilers, it's not something we can advise upon. Perhaps you want to pick the compiler that is available for free, if you don't already have one installed? (Also, please avoid typing in all capitals)

You need to install and set up a supported compiler using:

mex -setup
