How to save contents of nonscaler structure?

Hi There, I have a nonscalar structure of data that I wish to save. It seems the usual call to save does not work on nonscaler structures. Does anyone have a workaround?

My current structure is 1x4, with the second dimension being associated with different recording channels from my study struct(1).raw struct(2).raw ec.

Thank you in advance

What is the "usual call" that you are using? I think this Q&A might help: https://www.mathworks.com/matlabcentral/answers/29282-non-scalar-structures

"It seems the usual call to save does not work on nonscaler structures."

Yes it does:

save('nameOfFile.mat','nameofStruct')

Why do you think that this does not work?

You can just save() the structure. You do not need to use the -struct flag to save(). The -struct flag of save is for the particular case where you have a (scalar) structure whose individual fields you want to create as variables in a .mat file.

datastruct = load('YourMatFile.mat');
save('YourNewMatFile.mat', 'datastruct', '-struct')

load() of a .mat stored into a variable creates a scalar structure with one field for each variable stored in the .mat file, and save() with the -struct flag does the opposite, saving the individual fields into individual variables in a .mat file.
