The uses of fprintf and sprintf?

What are the exact uses for fprintf and sprintf? How do the two command differ and how should I know which command to use? Also using such a command to create a .txt file.

[per isakson]

The one creates a string in the work space the other prints to a file or the command window. The details are in the documentation.

Some background: the name "printf" comes from "PRINT Formatted" and occurs in many programming languages. In MATLAB this is extended with the two versions:

• fprintf means "File PRINT Formatted": use this for printing text to a file or the command window.
• sprintf means "String PRINT Formatted": use this for creating a MATLAB string ( character vector ).
