CHAR Convert to character array or string

Section: Type Conversion Functions

Usage

The char function can be used to convert an array into a string. It has several forms. The first form is 
   y = char(x)

where x is a numeric array containing character codes. FreeMat does not currently support Unicode, so the character codes must be in the range of [0,255]. The output is a string of the same size as x. A second form is 

   y = char(c)

where c is a cell array of strings, creates a matrix string where each row contains a string from the corresponding cell array. The third form is 

   y = char(s1, s2, s3, ...)

where si are a character arrays. The result is a matrix string where each row contains a string from the corresponding argument.

Example

Here is an example of the first technique being used to generate a string containing some ASCII characters 
--> char([32:64;65:97])

ans = 
 !"#$%&'()*+,-./0123456789:;<=>?@
ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`a

In the next example, we form a character array from a set of strings in a cell array. Note that the character array is padded with spaces to make the rows all have the same length. 

--> char({'hello','to','the','world'})

ans = 
hello
to   
the  
world

In the last example, we pass the individual strings as explicit arguments to char 

--> char('hello','to','the','world')

ans = 
hello
to   
the  
world
