Function char:

The function char does the opposite; it converts from any number type to the type char:

>> char(numequiv)

ans =

As the letters of the alphabet are in order, the character 'b' has the equal value of 98, 'c' is 99, and so on. Math can be completed on characters. For illustration, to get the next character in the collating sequence, 1 can be added either to the character or the integer:

>> numequiv = double('a');

>> char(numequiv + 1)

ans =

>> 'a' + 2

ans =
