Automating File Management in MATLAB:
Creating .csv file

In the following, we've written a code to create a .csv file to store our data. This is a template code that I am using for one of my project. 

Note: The loop allows for appending different modified versions of the data matrix to the file in each iteration. Its a template again. Must be modified as per need.

% Clear the command window and workspace

clc;

clear all;

% Example numeric matrix

data = [1, 2, 3; 4, 5, 6; 7, 8, 9];

% Column names

colNames = {'Thruput', 'Base', 'Col'};

% Specify the desired file name

filename = 'data.csv';

% Iterate three times

for iter = 1:3

    % Check if the file exists

    if isfile(filename) == 0

        % File does not exist, write column names and data

        writecell(colNames, 'data.csv');

        writematrix(data, filename, 'WriteMode', 'append');

    else

        % File exists, append modified data

        writematrix(data * (iter + 1), filename, 'WriteMode', 'append');

    end

end
