How to save fields of a struct through for loop iteration.

I have a struct with several field names.

data=

struct with fields:

'a': [100×1 double]

'b': [400×1 double]

.

.

etc.

I can save all the filed values to the same file as follow.

save(filename, 'a', 'b', ...)

but, since the field name are too many, I want to to save all of them by for loop. Is there any way I can do that? Thank you!

You don't need a loop, just use the -struct flag to save the fields of a scalar structure:

save(filename,'-struct','data')

When you load the file, make sure that you use an output argument:

data = load(filename);
