Created by George-Felix Leu in Community

Given an input text either as a string or as a cell array of strings, return a (1 x 26) matrix containing the number of occurrences of every letter ('a' to 'z'). The counting should be case insensitive, e.g. no difference between 'a' and 'A' should be made.
