How to map a scalar to a vector?

I want to map a letter to a a vector.

Example: a is mapped to [ 0 0 0 0 1]

b ia mapped to [0 0 0 1 0] and so on.

The containers.Map function does not help me with this regard. Is there any other way to do the mapping?

Thanks in advance!

Map = dec2bin(('a' :'z') - 'a' + 1, 5);

Word = 'hello' ;
Map(Word(:) - 'a' + 1,:)

Thanks. This answers my question as posted. But do you know how I should do it if I have other than just english alphabets? Or other characters? In gerneral, a scalar to vector mapping..

[Walter Roberson]

Create a character vector that contains all of the permitted characters. You can build it in pieces using [] if that helps.

Then

Map = dec2bin(1:numel(PermittedChars)) ;

[~, idx] = ismember(Word, PermittedChars);
Result = Map(idx, :);
