how to square a number in matlab

To square a number in Matlab, you can simply raise it to the power of 2 using the "^" operator or by using the "power" function.

Here's an example:

main.m
x = 5;
y = x^2; % or y = power(x,2);
disp(y);
46 chars
4 lines

This will output the value of y which is the square of x (25 in this case).
