how can i do this?

Answer 1

Here, at least this can possibly run.

Truth_Taple_mapping  = {'T' '0' '0' '0' 'G' '0' '0' 'G' '0'};
dna_stego={'ATG' 'TCG' 'ATC' 'TTC' 'ACC' 'CCC' 'ACC' 'AAC' 'CAG' 'ATC'};

get_codon = ???? % am i supposed to guess what this is?

for m=1:numel(Truth_Taple_mapping) % j is never used as an index
	if ~strcmp(Truth_Taple_mapping{m},'0') % the char '0' is not the number 0
		for k=1:numel(dna_stego) % none of these length variables are defined
			num=get_codon(dna_stego{k});
			if (num==1)
				temp=dna_stego{k};
				temp(3)=Truth_Taple_mapping{m}; % i is an invalid index since it's complex
				dna_stego{k}=temp ;
			end
		end
	end
end

Without knowing what is actually being done, there isn't any way to troubleshoot or simplify the code. All I can do is fix the obvious errors.

i run the code but not working

Truth_Taple_mapping = {'T' '0' '0' 'G' '0' '0' 'G'};

dna_stego={'ATG' 'TCG' 'ATC' 'TTC' 'ACC' 'CCC' 'ACC' 'AAC' 'CAG' 'ACC'}

%get_codon = ???? % am i supposed to guess what this is?

for m=1:numel(Truth_Taple_mapping) % j is never used as an index

iTruth_Taple_mapping = {'T' '0' '0' 'G' '0' '0' 'G'};

dna_stego={'ATG' 'TCG' 'ATC' 'TTC' 'ACC' 'CCC' 'ACC' 'AAC' 'CAG' 'ACC'}

%get_codon = ???? % am i supposed to guess what this is?

for m=1:numel(Truth_Taple_mapping) % j is never used as an index

if ~strcmp(Truth_Taple_mapping{m},'0') % the char '0' is not the number 0

for k=1:numel(dna_stego) % none of these length variables are defined

num=get_codon(dna_stego{k});

if (num==1)

temp=dna_stego{k};

temp(3)=Truth_Taple_mapping{m}; % i is an invalid index since it's complex

dna_stego{k}=temp ;

end

end

end

end

i run the code but not working

the output is{ 'ATG' 'TCG' 'ATC' 'TTC' 'ACG' 'CCG' 'ACG' 'AAC' 'CAG' 'ACG'}

and must be

{ 'ATG' 'TCT' 'ATC' 'TTC' 'ACG' 'CCC' 'ACC' 'AAC' 'CAG' 'ACG'}

the

TCG,TCC,ACC,CCC that can be change

As I noted, I don't know what the function get_codon() is or what criteria it uses for determining its output state.
