Error using containers.Map
Unsupported key specified.  See documentation for valid key types.

I don't know how to get pass this error, I have tried using both cellfun(@str2num,k1&2); aswell as [strcat({' '}, num2str(k1&2))] to get the keys into supported key but I still get the same message. If anyone could help that would be fantastic.

What is M1? i.e. what also is the type of k1 and k2?

'char', 'double', 'single', 'int32', 'uint32', 'int64', or 'uint64'. are the supported key types for a containers.Map

M1 is a cell array, and k1&k2 are char's As you can see I am trying to link the keys in columns 1 & 5 to the values in columns 2:4 & 6:11. If I look at the document both keys in char form are accepted, perhaps not my overall matrix (M1 - cell array). I will keep on working on it - if you have any other advise that would be fantastic thanks Adam.
