generate a code that performs a linear regression of a text file in matlab

Here is an example code in Matlab that performs a linear regression of a data from a text file:

main.m
% Load data from text file
data = load('data.txt');

% Separate data into X and Y variables
X = data(:, 1);
Y = data(:, 2);

% Plot the data for visualization
scatter(X, Y);
xlabel('X');
ylabel('Y');

% Perform linear regression
coefficients = polyfit(X, Y, 1);
intercept = coefficients(2);
slope = coefficients(1);

% Plot the regression line
hold on
plot(X, slope*X + intercept, '-r');
legend('Data', 'Linear Regression', 'Location', 'best');
445 chars
22 lines

Here, load() function is used to load the data from the text file, and the polyfit() function is used to perform the linear regression. Finally, we plot the data and the regression line to visualize the results. Note that you may need to adjust the path and file name in load() function depending on the location of your text file.
