Define a function:
The radius of a circle is passed to the function to input argument rad; the function computes the area of this circle and stores it in the output argument area. In the function header, we have reserved word function, then an output argument area followed by an assignment operator =, then the name of the function (similar as the name of the M-file), and then the input argument rad, that is the radius. As there is an output argument in the function header, anywhere in the body of the function we should assign a value to this output argument. This is how the value is returned from a function. In this situation, the function is easy and all we have to do is assign to the output argument area the value of the built-in constant pi multiplied by the square of the input argument rad.
The function can be exhibited in the Command Window by using the type command.
>> type calcarea
function area = calcarea(rad)
% This computes the area of a circle
area = pi * rad * rad;
Illustration of Built-in functions and help: To find out what a specific function does and how to call it, type help and then the name of function. Illustration: >> help si
User-Defined Functions which return a Single Value: We have seen the use of many functions in the MATLAB. We have used many built-in functions like fix, sin, abs, double, and

Format command: The format command can be used to control the spacing between the MATLAB command or expression and the outcome; it can be either compact or loose. >> format
Printing - matrices: For matrices, the MATLAB unwinds the matrix column by column. For illustration, consider the random 2 × 3 matrix as shown below: >> mat = randint(2,3,[
