What is sprintf in Matlab?

Chris Normand

sprintf is the same as fprintf except that it returns the data in a MATLAB string variable rather than writing it to a file. The format string specifies notation, alignment, significant digits, field width, and other aspects of output format.

What is Sprintf used for in MATLAB?

str = sprintf( literalText ) translates escape-character sequences in literalText , such as n and t . It returns all other characters unaltered. If literalText contain a formatting operator (such as %f ), then str discards it and all characters after.

What is difference between sprintf and fprintf?

The only difference between sprintf() and printf() is that sprintf() writes data into a character array, while printf() writes data to stdout, the standard output device.
