See the documentation on the csvwrite (link) function. It was introduced prior to R2006a, so you should have access to it. There are similar functions linked to in and at the end of that documentation page.

At present, csvwrite (documentation) is not recommended. If one has a newer version of MATLAB (2019a or later), writematrix (documentation) is the preferred way.

Thanks! Would I just call on the function several times then, like:
csvwrite('filename.csv',variable1,0,1)
csvwrite('filename.csv',variable2,0,2)
etc?

This is a stupid bruteforce method, if you find a better one please share. I have seen people just pointing to the default matlab way where you can save one variable. What if you have 1000's of variable that will take all the time. I hope someone will share a better code
Please use the following link: https://www.mathworks.com/matlabcentral/fileexchange/28343-column-converter-for-excel
for downloading xlscol function
clear all; close all; clc;
current_dir = pwd;
[Filename, Pathname] = uigetfile('Select File'); % select file
file_to_be_loaded = [Pathname '\' Filename]; % get file path and name
load(file_to_be_loaded); % load file
Filename
clear Pathname file_to_be_loaded current_dir
vars=who;
sheet = 1;
for n=1:size(vars)
n
xlRange = [xlscol(n) '1'];
xl_range = [xlscol(n) '2'];
xlswrite([Filename(1:end-4) '.xlsx'],cell(vars(n)),sheet, xlRange)
xlswrite([Filename(1:end-4) '.xlsx'],eval(char(vars(n))),sheet, xl_range)
end

A better way is to put the variables in a matrix, and export the data. See this thread:
https://uk.mathworks.com/matlabcentral/answers/281156-how-can-i-export-a-matrix-as-a-csv-file
xout1 = [1 2 3]
yout1 = [4 5 6]
m = [xout1,yout1]
csvwrite('filename.csv',m)
