IS Functions for Strings:

There are many functions for strings, that return logical true or false. The function isletter returns the logical true when the character is a letter of the alphabet. The function isspace returns the logical true when the character is a whitespace character. When strings are passed to such functions, they return the logical true or false for each and every element, or, in another words, each and every character.

>> isletter('a')

ans =


>> isletter('EK127')

ans =

1  1  0  0  0

>> isspace('a b')

ans =

0  1  0
