MATLAB: How to save the variable from the workspace into csv or excel file

Question

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');

Answer 1

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().
