convert vector of character to number

hello

how to covert vectro cell ['A' 'A' 'A' 'B' 'B' 'A'] to numerical vector [1 1 1 2 2 1]

Answer 1

It depends on how you translate a word, for example:

% s in this form is not a cell, but a character array
s=['A' 'A' 'A' 'B' 'B' 'A']

s = 'AAABBA'

abs(s)-abs('A')+1

ans = 1×6

1 1 1 2 2 1

Are the inputs always single characters? Are the inputs only A or B? Are the inputs always letters? Does case matter?

Here's a start for a method. It's compact and case-insensitive, but note that the outputs will probably be unexpected if the inputs aren't letters or single characters.

bunchofletters = {'A' 'A' 'A' 'B' 'B' 'A'};
bunchofnumbers = double(lower([bunchofletters{:}]))-96

bunchofnumbers = 1×6

1 1 1 2 2 1

Without knowing what the requirements are, I'm going to leave the task of making it fit for purpose up to someone who knows what the purpose is.
