Hello there,
I'm a newbie in Matlab, so please bare with me.
My problem: I have one structure array, with several fields each of different length. Each array contains values which can range between -1000 and 7000. (it's data from an experimental setup with so and so many repetitions, and each repetition gives me a different number of datapoints. I save the results from each repetition in a new field.)
I want to delete the values below zero in each field. But I just don't know how to do it; how to delete just specific elements from a field instead of the whole thing? Please help?! Thanks!

One way, assuming ALL fields need to have this applied:
structfun(@(x)x(x>=0),your_struct,'uni',false);

How would you do it with Matlab Coder that does not support anonymous functions?

Loop over fieldnames() of the structure and use dynamic field names (if those are supported.)
