addition of 1 & 4th column data from a text file, read text file from desktop in matlab

To perform the addition of the 1st and 4th column data from a text file in MATLAB, you can use the following code:

main.m
% Path to the text file on your desktop
filePath = 'C:\Users\YourUsername\Desktop\filename.txt';

% Read the data from the text file
data = dlmread(filePath);

% Extract the 1st and 4th columns
column1 = data(:, 1);
column4 = data(:, 4);

% Perform the addition
result = column1 + column4;
290 chars
13 lines

In the above code, the 'filePath' variable should be modified to the actual path of your text file on the desktop. The 'dlmread' function is used to read the data from the text file, assuming that the data is space-delimited.

After reading the data, the first column is extracted into the 'column1' variable, and the fourth column is extracted into the 'column4' variable. Finally, the addition is performed by adding 'column1' and 'column4', and the result is stored in the 'result' variable.

Please note that if your text file has a different delimiter (e.g., comma), you can use the 'csvread' function instead of 'dlmread' and specify the delimiter using the 'delimiter' parameter.
