How can I prevent MATLAB Coder to generate variable size code for a simple number insertion into a string?
for i=1:4
In the generated C code it uses a lot of functions like emxutil to determine the size of the generated string for sprtintf.
I just want to say that i is only one digit. How can I do that?!
The followings also do not work
Using the following also gives an error for generating code that LHS is fixed sized but RHS is varying:

If you know that it is a single digit then do not use that technique. Instead you can use
name = ['Data', char(i+'0'), '.bin']
Or if you really need to
name = 'DataX.bin';
name(5) = char(i+48);

Thank you. Your code works very well with one digit.
I just tested the following again. It works good also and can be used for more digits, and it does not use var size stuff.
