appendsave

Dear all, I have data store in a mat file (i.e.,subject01_dataset.mat) . Under the mat file, each data were store 1) Patient_FullData.auxilaryData 2) Patient_FullData.reshape
After some processing, I want to store the result as Patient_FullData.result Thus the following line were utilized
save ('SC4001E0_dataset.mat', 'Patient_FullData.result', '-append');
However, I got the following error
'Patient_FullData.data' is not a valid variable name.
May I know how to mitigate this issue

You cannot save() a field in a structure, and you cannot use save() to appened to an existing struture.
If you need to appened on to an existing array in a .mat file, consider using matFile()
