"I have that feeling, that i'm going to be referred to the FAQ where it says not to do this."
Yes
Because when someone designs their data such that they force themselves into writing slow, complex, obfuscated, buggy code that is hard to follw and difficult to debug, some other helpful people are likely to suggest better ways of designing their data and code:
Not just helpful other users, but also the MATLAB documentation reccomends against your approach "A frequent use of the eval function is to create sets of variables such as A1, A2, ..., An, but this approach does not use the array processing power of MATLAB and is not recommended. The preferred method is to store related data in a single array."
"But I honestly do not know how I would transfer the advice given there to my problem."
The lede to that tutorial states "The most common alternative is to use simple and efficient indexing."
Have you tried using indexing instead of numbering your variables? I very much doubt that you sat and wrote out the names of 300 variables, so most likely your situation fits into either of these common cases:
- the arrays were load-ed from file, or
- the arrays were created in a loop.
Once you explain the most important information missing from your question (how did those arrays get into the workspace?) then someone can show you a better approach that will make repeating your code easy and efficient.
