The fprintf function allows you to "write" information to the screen for the user to view. This very important when user interaction is involved. The 'f' in printf stands for formatted. 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.

Concatenate multiple character vectors together using the [] operator.

Argument fid is an integer file identifier obtained from fopen. It may also be 1 for standard output the screen or 2 for standard error. See fopen for more information. Omitting fid causes output to appear on the screen. Format String The format argument is a string containing C language conversion specifications. A conversion specification controls the notation, alignment, significant digits, field width, and other aspects of output format. The format string can contain escape characters to represent non-printing characters such as newline characters and tabs. Flags You can control the alignment of the output using any of these optional flags. Character Description Example A minus sign - Left-justifies the converted argument in its field.

Lesson index Introduction Strings Formatted output Summary. The format conventions follow the C language function fprintf. Otherwise the next fprintf continues exactly where the last one finished which can be very useful.
