I have data from sensors and I want to store them on a .txt file (or better in a .mat file). I am using fwrite but it is not supported by code generator. I have seen that I can use coder.extrinsic but it does not work, or coder.ceval() but it does...

For C I/O to work, the debugger must be able to set breakpoints at the two special labels C$$IO$$ (in function writemsg) and C$$EXIT (in function abort). It's not necessary that these breakpoints be in RAM, but it is necessary that the debugger be able to set these breakpoints....

Using fopen for all .CSV files in a single folderThank you once again Per for your great contribution. I believe this is what I needed to get it to work. Unfortunately, I am going to sleep now but will test it first thing in the AM.Why...
But if you are not satisfied with this decision, and you want to use fread/fwrite instead of i/o-streams, you can get some inspiration from unique_ptr, and write your own File, which will be optimized for your personal needs, convenient, readable, and safe. What is the result?
