How can I find each character's index within a matrix, from a vector of characters?

I have a matrix of characters
Letters = [A, B, C;
D, E, F;
G, H, I];
Secondarily, I will have a vector of letters, and I need to find the index of each letter in the matrix of Letters. For example,
vec = [A, C, H, I], or it could be any combination of letters. I'm sure there is a simple answer that I am missing. I know normally you need to call the character with a string, but I don't know how to call, say vec(1) as a string (as in, idx = find(Letters == vec(1)), and it would return 1, for A), which I think would solve the problem.

Letters =['ABC'; 'DEF'; 'GHI']
vec = 'ACHI'
[r, c] = find(Letters == vec(i));
fprintf("%s: (%d, %d)\n", vec(i), r, c)
