Plz help how can i do this

I have this code

TTmap = {'T' '0' '0' 'T'};
dna_stego={'ATA' 'ACC' 'AAC'  'AAC' 'CAG' 'ACC'};
amino_acid={'CG' 'GG' 'TC' 'CC' 'AC' 'GC' 'CT' 'GT'};
TTmap(end+1:numel(dna_stego)) = {'0'};
ttnonzero = ~strcmp(TTmap,'0').';
dna_stego_out = dna_stego;
count=1;
for k = 1:numel(dna_stego)
	aamatches = ismember(dna_stego{count}(1:2),amino_acid);
	if (ttnonzero(k)~=0)
        if (aamatches==1)
            dna_stego_out{count}(3) = TTmap{k};
        else
            while(aamatches~=1)
                count=count+1;
                aamatches = ismember(dna_stego{count}(1:2),amino_acid);
                
            end
            dna_stego_out{count}(3) = TTmap{k};
        end
    else
        count=count+1;
  end
    
end

and I get the error

Index exceeds matrix dimensions.

Error in test2 (line 12)

aamatches = ismember(dna_stego{count}(1:2),amino_acid)

I want that the output should be

dna_stego_out={'ATA' 'ACT' 'AAC' 'AAC' 'CAG' 'ACT'};

@eman baky,

Your quesiton is not eassy to read bcause you have formatted parts of your question as code that should not be. I think you meant to write:

____________________

the output is

dna_stego_out = 
    'ATA'    'ATA'    'ATC'    'AAC'    'CAG'    'ACC'

I want it to be

dna_stego_out = 
    'ATA'    'ATA'    'ATT'    'AAC'    'CAG'    'ACT'

____________________

Please explain what you are trying to do, and explain the logic basis for the output which you want.

I think I fixed the formatting.

I have three vectors

TTmap = {'0' 'T' '0' 'T'};

dna_stego={'ATA' 'ACC' 'AAC' 'AAC' 'CAG' 'ACC'};

amino_acid={'CG' 'GG' 'TC' 'CC' 'AC' 'GC' 'CT' 'GT'};

I wanna replace the value in TTmap with dna_stego_out{n}(3) but under two condition

The first one I replace if TTmap is not equal to zero and if equal zero I do not anything in dna_stego

second one dna_stego{count}(1:2) one of amino_acid if not I will chack another one in dna_stego

in this case, the output suppose be

dna_stego_output

{ 'ATA' 'ACT' 'AAC' 'AAC' 'CAG' 'ACT'}

Try this:

TTmap = {'T' '0' '0' 'T'};
dna_stego={'ATA' 'ACC' 'AAC'  'AAC' 'CAG' 'ACC'};
amino_acid={'CG' 'GG' 'TC' 'CC' 'AC' 'GC' 'CT' 'GT'};
TTmap(end+1:numel(dna_stego)) = {'0'};
ttnonzero = ~strcmp(TTmap,'0').';
dna_stego_out = dna_stego;
count=1;
for k = 1:numel(dna_stego)
	% Get first two characters of the k'th cell contents.
	thisString = dna_stego{count}(1:2);
	fprintf('Checking if %s is in the "amino_acid" cell array.\n', thisString);
	% See if this character pair matched any pairs in amino_acid.
	[ia, index] = ismember({thisString}, amino_acid);
	if ia
		fprintf('   Found %s at index %d, which is "%s".', thisString, index, amino_acid{index});
	else
		fprintf('   Did not find %s in amino_acid.\n', thisString);
	end
	% Uncommented stuff below I didn't bother to figure out.
% 	if (ttnonzero(k)~=0)
%         if (aamatches==1)
%             dna_stego_out{count}(3) = TTmap{k};
%         else
%             while(aamatches~=1)
%                 count=count+1;
%                 aamatches = ismember(dna_stego{count}(1:2),amino_acid);
%                 
%             end
%             dna_stego_out{count}(3) = TTmap{k};
%         end
%     else
%         count=count+1;
%   end
    
end
