return in the command window a matrix of the pairwise linear correlation coefficients between the variables age, attendance, 1st exam score, 2nd exam score and o/all score using function corr. in matlab

You can return a matrix of the pairwise linear correlation coefficients between variables age, attendance, 1st exam score, 2nd exam score, and o/all score using the corr function in MATLAB as follows:

main.m
% Create a matrix with data for the variables age, attendance, 1st exam score, 2nd exam score, and o/all score
data = [age, attendance, first_exam_score, second_exam_score, overall_score];

% Use the corr function to calculate the pairwise linear correlation coefficients matrix
correlation_matrix = corr(data);

% Display the correlation coefficients in the command window
disp(correlation_matrix);

Replace age, attendance, first_exam_score, second_exam_score, and overall_score with the actual data vectors or matrices in your MATLAB workspace.

Make sure to have the variables defined with appropriate data before running this code snippet.
