Hi,
I am using the code below to save one of the variable from the workspace into the
excel file but struggling to save it, what it is doing is saving some gibrish into excel rather then the data.
Code:
close all; clear all; clc;
folder = fullfile('D:','Velocity_Analysis','paraViewpractise');
files = dir( fullfile(folder, '*.csv') );
for ii = 1:length(files)
data = readmatrix(fullfile(files(ii).folder,files(ii).name), 'NumHeaderLines', 1)
res(:,ii)= data(:,3);
end
filename='workspace_variable.xls';
save(filename,'res');
winopen('workspace_variable.xls');

save() is for saving in a .mat file. You need writematrix() for xls
filename='workspace_variable.xls';
writematrix(res, filename);
For releases older than R2019a, use xlswrite().

R2020a, yea should work, as all the FAQs answers same as yours and I have tried different ways, I ended up doing it manually. Thanks anyway! I bother you with something else if i stuck again. Thanks for your support!

You may consider attaching your complete code including the line writematrix. Maybe it will give some hints of the issue.
