![]() ![]() Used with o, x or X specifiers the value is preceeded with 0, 0x or 0X respectively for values different than zero. If no sign is going to be written, a blank space is inserted before the value. ![]() By default, only negative numbers are preceded with a - sign. Left-justify within the given field width Right justification is the default (see width sub-specifier).įorces to preceed the result with a plus or minus sign ( + or -) even for positive numbers. precision and modifiers (in that order), which are optional and follow these specifications: ![]() The format specifier can also contain sub-specifiers: flags, width. The number of characters written so far is stored in the pointed location.Ī % followed by another % character will write a single % to the stream. The corresponding argument must be a pointer to a signed int. Use the shortest representation: %E or %F Use the shortest representation: %e or %f Scientific notation (mantissa/exponent), uppercase Scientific notation (mantissa/exponent), lowercase Where the specifier character at the end is the most significant component, since it defines the type and the interpretation of its corresponding argument: It can optionally contain embedded format specifiers that are replaced by the values specified in subsequent additional arguments and formatted as requested.Ī format specifier follows this prototype: format C string that contains the text to be written to the stream. Parameters stream Pointer to a FILE object that identifies an output stream. ![]() If format includes format specifiers (subsequences beginning with %), the additional arguments following format are formatted and inserted in the resulting string replacing their respective specifiers.Īfter the format parameter, the function expects at least as many additional arguments as specified by format. You can find more information about the available formatting codes in the MATLAB documentation.Writes the C string pointed by format to the stream. 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. 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. ![]()
