The sprintf function behaves like its ANSI C language namesake with these exceptions and extensions. This table lists the escape character sequences you use to specify non-printing characters in a format specification. The following tables describe the nonalphanumeric characters found in format specification strings. Hexadecimal notation (using uppercase letters A- F) Hexadecimal notation (using lowercase letters a- f) The more compact of %e or %f, as defined in. You can control the width and precision of the output by including these options in the format string.Ī digit string specifying the minimum number of digits to be printed.Ī digit string including a period (.) specifying the number of digits to be printed to the right of the decimal point.Ĭonversion characters specify the notation of the output.Įxponential notation (using a lowercase e as in 3.1415e+00)Įxponential notation (using an uppercase E as in 3.1415E+00) Left-justifies the converted argument in its field. You can control the alignment of the output using any of these optional flags. You specify these elements in the following order: The format string can contain escape characters to represent non-printing characters such as newline characters and tabs.Ĭonversion specifications begin with the % character and contain these optional and required elements:
A conversion specification controls the notation, alignment, significant digits, field width, and other aspects of output format. The format argument is a string containing C language conversion specifications.
Sprintf is the same as fprintf except that it returns the data in a MATLAB string variable rather than writing it to a file. errmsg is an empty matrix if no error occurred. The sprintf function returns an error message string errmsg if an error occurred. = sprintf(format,A.) formats the data in matrix A (and in any additional matrix arguments) under control of the specified format string, and returns it in the MATLAB string variable s.
