joins the strings horizontally and produces

Hello world

The statement

v = [s; 'world']

joins the strings vertically and produces

Hello

world

Notethatablankhastobeinsertedbeforethe'w' in h and that both words

v have to have the same length. The resulting arrays are both character

arrays;

h is 1-by-11 and v is 2-by-5.

To m anipulate a body of text containing lines of different lengths, you have

two choices—a padded character array or a cell array of strings. When

creating a character array, you must make each row of the array the same

length. (Pad the ends of the shorter rows with spaces.) The

char function do es

this padding for you. For example,

S = char('A','rolling ','stone','gathers', 'momentum.')

produces a 5-by-9 character array:

rolling

stone

gathers

momentum.

Alternatively, you can store the text in a cell array. For example,

C = {'A';'rolling';'s tone';'gathers';'mom entum.'}

creates a 5-by-1 cell array that requires no padding because each row of the

array can have a different length:

4-15
