MATLAB: Saving structure as a .mat file with matrices, strings and numbers

loadMATLABsavestructures

I have a very large structure full of data that fails to save as a .mat file. Some feilds have strings while other have scalars while others have matrices.
save('data.mat', '-struct', s)
Save does not workk in this case, I suspect because its not a scalar but in the save help page we can save structures.
The error I get is:
"Error using save"
"Must be a string scalar or character vector."
and if I add the '-struct' delimiter I get the error:
Error using save
The argument to -STRUCT must be the name of a scalar structure variable.

There are two issues here. If you read the doc it specifies that the struct must be scalar (each field is allowed to be any type or size). It also still requires you to enter the variable name as a char.
save('data.mat', '-struct', 's')%will only work if s is a scalar struct
If your struct is an array, you will either have to make it a scalar struct, or avoid the struct syntax.
%example:
s_wrapped=struct('content',s);
save('data.mat', '-struct', 's_wrapped')
