show the result in matlab

In MATLAB, to display the result of a computation or variable value, you can use the disp() function.

main.m
% define a variable
x = 5;

% display the variable value
disp(x);

% perform a computation and display the result
y = x^2 + 3*x - 2;
disp(y);

You can also use fprintf() to display more complex output with formatting options.
