fprintf

Displays variable text centered on masked subsystem icon

Syntax

fprintf(t)

fprintf(formatspec,var)

Description

fprintf(t) displays formatted text centered on the icon.

fprintf(formatspec,var) formats var as specified in formatspec.

Examples

Display Text on Block Icon

Display the text Hello on the icon.

fprintf('Hello');

Display Formatted Text on Block Icon

Convert the character a to an integer 97 and display it on the block icon.

myvar = 'a'
fprintf('hello = %d',myvar);

Input Arguments

t — Text that appears on the block

character vector | string

Text that appears on the block is specified as a string or a character vector.

Data Types: char | string

formatspec — Formatting character for the variable

character vector | string

Conversion character for the variable is specified.

Formatting Operator

A formatting operator starts with a percent sign, %, and ends with a conversion character. It is mandatory to specify the conversion character. Optionally, you can specify identifier, flags, field width, precision, and subtype operators between % and the conversion character. Spaces are invalid between operators and are shown here only for readability.

Conversion Character

This table shows conversion characters to format numeric and character data as text.

Value Type	Conversion	Details
Integer, signed	%d or %i	Base 10
Integer, unsigned	%u	Base 10
	%o	Base 8 (octal)
	%x	Base 16 (hexadecimal), lowercase letters a–f
	%X	Same as %x, uppercase letters A–F
Floating-point number	%f	Fixed-point notation (Use a precision operator to specify the number of digits after the decimal point.)
	%e	Exponential notation, such as 3.141593e+00 (Use a precision operator to specify the number of digits after the decimal point.)
	%E	Same as %e, but uppercase, such as 3.141593E+00 (Use a precision operator to specify the number of digits after the decimal point.)
	%g	The more compact of %e or %f, with no trailing zeros (Use a precision operator to specify the number of significant digits.)
	%G	The more compact of %E or %f, with no trailing zeros (Use a precision operator to specify the number of significant digits.)
Characters or strings	%c	Single character
	%s	Character vector or string array. The type of the output text is the same as the type of formatSpec.

Data Types: char | string

var — Variable containing the value is specified

character vector | string

The variable is formatted as per the formatting character specified in formatspec.

Note

While this fprintf function is identical in name to its corresponding MATLAB^® function, it provides only the functionality described on this page.
