There is no attached file. Please do not post code as screenshot, because this is less useful for creating an answer. Whenever you mention an error in the forum, post a complete copy of the message instead of letting the readers guess, what you see.

You didn't attach anything. And what do you mean by 'compile'? Are you using Matlab Coder to produce C++ code?

mu1 isn't defined at all in the code you give so obviously using it as an index will give an error.

mu1 is used before it is defined. What is the prupose of:

real(mu1) = -log(1.3);
imag(mu2) = log(1.8);

? real() is a function and you cannot assign a value to the output of a function. Do you mean:

mu1 = -log(1.3) + 1i * log(1.8);

?

Then omit this line, which actually replaces a value by its value:

mu1 = real(mu1) + i .* imag(mu1);
