Convert to character array (string)
Syntax
Description
S = char(X)
converts the array X
that contains positive integers representing character codes into a MATLAB character array (the first 127 codes are ASCII). The actual characters displayed depend on the character set encoding for a given font. The result for any elements of X
outside the range from 0 to 65535 is not defined (and can vary from platform to platform). Use double
to convert a character array into its numeric codes.
S = char(C),
when C
is a cell array of strings, places each element of C
into the rows of the character array s
. Use cellstr
to convert back.
S = char(t1, t2, t3, ...)
forms the character array S
containing the text strings T1
, T2
, T3
, ...
as rows, automatically padding each string with blanks to form a valid matrix. Each text parameter, T
i
, can itself be a character array. This allows the creation of arbitrarily large character arrays. Empty strings are significant.
Remarks
Ordinarily, the elements of A
are integers in the range 32:127, which are the printable ASCII characters, or in the range 0:255, which are all 8-bit values. For noninteger values, or values outside the range 0:255, the characters printed are determined by fix(rem(A, 256))
.
Examples
To print a 3-by-32 display of the printable ASCII characters,
ascii = char(reshape(32:127, 32, 3)') ascii = ! " # $ % & ' ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \ ] ^ _ ' a b c d e f g h i j k l m n o p q r s t u v w x y z { | } ~
