loop through files not working correctly.

3 views (last 30 days)
Hello,
I'm trying to convert .xls files in a folder into .mat files, but the code is not looping through the files correctly.
The .xls files are called cycle1, cycle2, cycle3...etc and they all have different numbers of rows.
sch_cycle and nrows are not changing for each file. It creates all the .mat files but they are all the same corresponding to cycle1.xls.
Could anybody tell me what is going wrong?
Sincere thanks
John
x = cellstr(ls('*.xls'));
for k = 1:length(x)
sch_cycle=xlsread('C:\Autonomie practice\cycle1.xls','Input_data');
nrows = size(sch_cycle,1)-1;
sch_grade=[0,0;nrows,0];
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'],'sch_cycle','sch_grade','sch_key_on','sch_metadata');
end

Your code reads cycle1.xls every time it starts the loop. It needs to read each file in turn - probably like this:
sch_cycle = xlsread(x{k}, 'Input_data');
since the call to ls suggests that you expect to be working in the directory with the .xls files.
