Hi there,

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

In the .mat file it is saving

fn
k
nrows
sch_cycle
sch_grade
sch_key_on
sch_metadata
x

How could I make it only save these only?

sch_cycle
sch_grade
sch_key_on
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

The leading quote before sch_key_on is missing.
