how to calculate the range of a matrix in matlab

To calculate the range of a matrix in MATLAB, you can use the range function. This function returns the difference between the maximum and minimum elements of a matrix. Here's an example code block that demonstrates how to use range:

main.m
% create a sample matrix
A = [1 2 3; 4 5 6; 7 8 9];

% calculate the range of A
r = range(A);

disp(r); % display the result
125 chars
8 lines

This code will output 8, which is the difference between the minimum element (1) and the maximum element (9) of the matrix A.
