This means you can "format" how the data is printed in such a manner as to make it easy to read. The fprintf function is used for printing information to the screen. The fprintf function prints an array of characters to the screen:. We often use the fprintf statement to show the user information stored in our variables. Below are several examples of printing information from variables using fprintf. By putting a decimal point and a number in the format command, you are telling the program to print only two decimal places. The following ways to "print" information are also available in Matlab, but are "frowned" upon, except for rapid debugging of a program. Any time you print information, you should make sure it is of interest to the user of the program every time the code is run. For example a function that compute pi should never use fprintf. Instead, such a function should return the value of pi for use by other parts of the program. If this approximated value of pi is of interest to the user, then the main program can print the result. Notice how the second example prints "the sum is XX" every time the add function is called.

If a variable contains an empty array, disp returns without displaying anything.
