Hello,

I want to create a Look Up Table using cells. This can be better illustrated with an example.

I have a cell of string values c = {'1','3'} that are part of an alphabet b = {'5','3','1'}. This alphabet maps to a = {'E10','E11','E12'}.

The order is important here so I want the mapping '5' -> 'E10', '3' -> 'E11' and '1' -> 'E12'.

I am expecting the output to be 'E12', 'E11'.

How do you think I can do this? Thanks in advance!!

This is easy via a containers.Map object:

>> a = {'E10','E11','E12'};
>> b = {  '5',  '3',  '1'};
>> obj = containers.Map(b,a);

and accessing the values is easy:

>> obj('3') % one value
ans =
E11
>> values(obj,{'1','3'}) % multiple values.
ans = 
    'E12'    'E11'

Thanks a lot for the answer! That way is much simpler than the one I found!
