Section: Type Conversion Functions
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.
--> char([32:64;65:97]) ans = !"#$%&'()*+,-./0123456789:;<=>?@ ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`a --> quit
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
-->
quit
In the last example, we pass the individual strings as explicit
arguments to char
--> char('hello','to','the','world')
ans =
hello
to
the
world
-->
quit
