Hi All,
Is there any way of programmatically obtaining the allowed inputs in a given Matlab function, more specifically the Name-Value inputs? I'm trying to make a feature engineering App, that allows a user to carry out feature engineering without any coding.
Thanks, James

Hi both, what I mean, is that if I pass in genrfeatures (for example), is it possible for it to return the Name-Value Arguments in a structure, i.e. Target Learner - {"linear","bag","gaussian-svm"}, and so on. So that I can allow a user to select the options that apply to them

Not in general. If a function uses the modern arguments block (since R2019b), this is possible. But many users are running older Matlab versions, where these blocks cause errors. Therefore this block cannot be expected to exist yet.

Hi Jan, I'm developing this in 2022a, and the users that will be using it in my company are using 2022a as well. What I am trying to get is the Name-Value pairs specifically, i.e. if I pass in genrfeatures (for example), is it possible for it to return the Name-Value Arguments in a structure, i.e. Target Learner - {"linear","bag","gaussian-svm"}, and so on. So that I can allow a user to select the options that apply to them.
