explain sm=500 in matlab

In MATLAB, sm=500 is a variable assignment statement, which assigns the value 500 to the variable named sm.

After executing this statement, the variable sm will hold the value 500 until its value is changed by another assignment statement. This means you can use sm later in your MATLAB code to represent the value 500, such as doing some calculations with it or printing it out to the console.

Here is an example of using sm in MATLAB:

main.m
sm=500;
x=sm+10;
disp(x); % this will display 510 on the console
