fprintf

Display variable text centered on masked subsystem icon

Syntax

fprintf(text)
fprintf(formatSpec, var)

Description

The fprintf command displays formatted text centered on the icon and can display formatSpec along with the contents of var.

Note

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

formatSpec can be a character vector in single quotes, or a string scalar.

Formatting Operator

A formatting operator starts with a percent sign, %, and ends with a conversion character. The conversion character is required. 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 TypeConversionDetails

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.

Examples

The command

fprintf('Hello');

displays the text 'Hello' on the icon.

The command

fprintf('Hello = %d',17);

uses the decimal notation format (%d) to display the variable 17.
