Preventing unwanted variables being saved in .mat file

Hi there,

I am using the code below to create a .mat file.

In the .mat file it is saving

1. fn
2. k
3. nrows
4. sch_cycle
5. sch_grade
6. sch_key_on
7. sch_metadata
8. x

How could I make it only save these only?

1. sch_cycle
2. sch_grade
3. sch_key_on
4. sch_metadata

x = cellstr(ls('*.xls'));
for k = 1:length(x)
sch_cycle=xlsread('C:\Autonomie practice\cycle.xls','Input_data');
nrows = size(sch_cycle,1);
sch_grade=[0,0;nrows,0];
nrows = size(sch_cycle,1);
sch_grade=[0 0;nrows 0];
sch_key_on=[0 1; nrows 1];
[~,fn] = fileparts(x{k});
sch_metadata.name = fn;
sch_metadata.proprietary='public';
save([fn,'.mat']);
end

Thank you

save([fn,'.mat'],'sch_cycle','sch_grade',sch_key_on','sch_metadata');

Hello Jonathan,

Thank you for your reply. I tried this but I'm getting an error.

??? Error using ==> save

Argument must contain a string.

Error in ==> revised_convertfiles at 12

save([fn,'.mat'],'sch_cycle','sch_grade',sch_key_on','sch_metadata');

Would you know what is causing this?

The leading quote before sch_key_on is missing.
