How to create a structure of matrices within a loop

Dear all,

Using the following code, I would like to create a structure containing 3 matrices that are the result of a loop. I want these matrices to be named within this structure, e.g. 'A', 'B' and 'C'. What should I improve in my code?

for s0 = 1:3
    matrixOfCodes = cell(size(matrixOfNames,2), length(codePart1));
    for s1 = 1:size(matrixOfNames,2)
        for s2 = 1:length(codePart1)
            fullPath = strcat(codePart1{s2}, matrixOfNames{s0,s1}, codePart2{s2});
            matrixOfCodes{s1, s2} = fullPath;
        end
    end
m{s0} = matrixOfCodes;
matrixOfCodes = [];
end

C = {'A','B','C'};
S = struct();
for k = 1:numel(C)
    S.(C{k}) = whatever
end

Note that accessing data like this may be less convenient than simply using the existing arrays and indexing.

Dear Stephen,

Thank you for your response, however when I implement your idea I get an error: 'Argument to dynamic structure reference must evaluate to a valid field name'. My code now look like the one below:

database = {'A','B','C'};
m = struct();

for s0 = 1:numel(database)
    matrixOfCodes = cell(size(matrixOfNames,2), length(codePart1));
    for s1 = 1:size(matrixOfNames,2)
        for s2 = 1:length(codePart1)
            fullPath = strcat(codePart1{s2}, matrixOfNames{s0,s1}, codePart2{s2});
            matrixOfCodes{s1, s2} = fullPath;
        end
    end
m.(database) = matrixOfCodes;

end

@Joanna Przeworska: I fixed my answer. You will need this:

m.(database{s0}) = ..
%          ^^^^ index

Dear Stephen,

The code works now exactly as I expected. Thank you very much!

Kind regards,
