Hello,
I have searched around for a good couple of hours but I cannot figure out how to properly use getfield() to call on multiple fields.
What works:
getfield(MyStruct(8), 'field1')
or
getfield(MyStruct(8), 'field2')
Whwat does NOT work:
getfield(MyStruct(8), 'field1', 'field2')
Among many other variations... I have tried specific indexing, so on and so forth. MyStruct is a 1X44 with 10 fields.
Thanks in advance!

This function is genuinely buggy and does not work as advertised. You can pull up the code and fix it manually for your machine though, since the code for this function is accessible. I can show you how later if you need help.

I could look into that, even though I have never tried to edit a native function.
Anythign specific to watchout for when approaching this task?
Thanks!

Which version of MATLAB are you using? The documentation says that getfield() can access nested fields, not that you can retrieve multiple fields at a time.

I am using 2017a and 2017b.
I suppose I misinterpreted the description where it says: "....The getfield function supports multiple sets of field and fIndx inputs..."
But if you can only get one field at a time (per getfield() call), then I will stop trying.
Thank you!
