Search and replace values in cell array?

I have a cell array that is populated with 0's and letters. I and trying to write a script that will convert the different letters into different numerical values. The array is set up as below;

0 0 0 0 M

0 0 0 0 0

0 S 0 0 0

0 0 L 0 0

And i am trying to convert it to;

0 0 0 0 2

0 0 0 0 0

0 1 0 0 0

0 0 3 0 0

I can't search each column/row and replace manually as I will have an unknown amount of each. I tried using cellfun for this but as the isn't scalar I wasn't sure how. Any suggestions?

I believe cellfun should still work. Try setting 'UniformOutput' to false.

I'm using this script and the error below appears:

A(cellfun(@(elem) elem == 'M', A(:, :) 'UniformOutput', false), :) = {2};

Get error that subsindex doesnt work with class 'cell'.

Convert it to a matrix first in order to index into your cell array:

A(cell2mat(cellfun(@(elem) elem == 'M', A(:, :), 'UniformOutput', false))) = {2};

Here is what I see:

It worked, thanks!
