Manner, without reinitializing, through any additional matrix arguments. (columnwise) until all the elements are used up. The format string is cycled through the elements of A The fprintf function is vectorized for the case when input matrix A is The underlying C data type is a double rather than an unsigned integer.įor example, to print a double-precision value in hexadecimal, use a formatĢ. The underlying C data type is a float rather than an unsigned integer. The following non-standard subtype specifiers are supported for conversion Remarks The fprintf function behaves like its ANSI C language fprintf() namesake with certain exceptions and extensions.
It can contain ordinary alphanumeric characters along with escape characters, conversion specifiers, and other characters, organized as shown below:įor more information see "Tables" and "References". The format string specifies notation, alignment, significant digits, field width, and other aspects of output format. See fopen for more information.) Omitting fid from fprintf's argument list causes output to appear on the screen, and is the same as writing to standard output ( fid = 1) fprintf( format,A.) (It may also be 1 for standard output (the screen) or 2 for standard error. Argument fid is an integer file identifier obtained from fopen. fprintf returns a count of the number of bytes written. You can find more information about the available formatting codes in the MATLAB documentation.Fprintf (MATLAB Function Reference) MATLAB Function Referenceĭescription count = fprintf(fid, format,A.)įormats the data in the real part of matrix A (and in any additional matrix arguments) under control of the specified format string, and writes it to the file associated with file identifier fid. You can use a variety of formatting codes with fprintfIncluding codes for printing integers, floating-point numbers, and strings, as well as codes for controlling the output's alignment, width, and precision. The \n at the end of the format string tells fprintf to start a new line after printing the text.
#Format matlab fprintf code
The %f formatting code in the format string tells fprintf to print the value of x as a floating-point number, and the %s formatting code tells it to print the value of y as a string. This code will print the following text to the command window: Copy code The value of x is 3.141590 and the value of y is Hello, world!. These values can be variables or literals, and they will be inserted into the format string in place of the corresponding formatting codes.įor example, consider the following code: x = 3.14159 įprintf('The value of x is %f and the value of y is %s.\n', x, y) part of the syntax represents one or more values that you want to print. It can contain special characters that control the formatting of the output, such as newline characters ( \n), tab characters ( \t), and formatting codes for numbers and strings.
Here, format_string is a string that specifies the format of the text to be printed. The basic syntax for the fprintf function is: fprintf(format_string, A. It is similar to the disp function, but allows you to specify the format of the text that is printed. In MATLAB, the fprintf function is used to print formatted text to the command window or to a file.
