Saving the content of a cell array into a file

I want to write a content of a cell array into an m-file. I copied the content of a function file and save it in a cell array so as to make some modifications and then save it back into another function file. I would then pass the same input to the two separate functions (original and modified). I have a number of the modified functions called msize. If the result of the original function is different from the modified, ONE is assigned to the output array that compares the result otherwise ZERO is assigned. The code is returning only ONEs or ZEROs. But when I executed the code step-wise, it's returning correct results. I don't know perhaps the writing I made to the new function file does not allow writing of other files so that the first result is often repeated. See the code below:

function [killVector] = Tester(fname,mutants,tcase)
%%An edited version of an original function is called its mutant. 
% Test cases are generated and passed as "tcase" in this function while
% fname is the name of the function to be passed, mutants is the cell
% array of the mutants. The same test cases are passed to the original
% and each of its mutants. If the result of the original version is
% different from the mutant's, then the mutant is killed else alive. The
% killVector stores the vector of killing of each mutant. If the mutant is
% killed, its killing value is ONE but if it's alive, the value is ZERO
 num = numel(de2bi(numOfLines(fname)));
 msize=length(mutants);
 a=bin2dec(num2str(tcase(1)))+1;
 b=bin2dec(num2str(tcase(2:5)))+1;
 c=bin2dec(num2str(tcase(6:end)))+1;
 %
 %disp(realResult);
 nfname='mutantfname.m';
 T=zeros(msize,1);
 values=zeros(msize,1);
 i = 1;
 while(i <= msize/3)
 %for i=1:msize
     chr=mutants{i};
     op=bin2dec(num2str(chr(1)))+1;
     lnum=round(bin2dec(num2str(chr(2:num+1)))+1);
     choice=round(bin2dec(num2str(chr(num+2:end)))+1);

       if (op==1)
              mutated=arithRep(fname,lnum,choice);
       elseif (op==2)
              mutated=relRep(fname,lnum,choice);
       end

       writeToFile(nfname,mutated);
   %     filenames=strcat('m',num2str(i),'.m');
    %    writeToFile(filenames,mutated);
       mresult=mutantfname(a,b,c);
  %      delete('mutantfname.m');
  %      clear mutated;
       values(i)=mresult;
       r=randi(1);
       realResult=sumOfRoots(a,b,c);% Try to shift it inside the loop after write
       if isequal(realResult,mresult)
           y=0;
       else
           y=1;
       end
       T(i)=y;
       i = i + 1;
   end

   %killVector=T';
   killVector=values';
  end

You increase your chances to get a good answer if you supply enough sample input data

 fname, mutants, tcase, ...

so that we may run your code

I have attached

• the file that fname represents. One only need to assign fname to the name of the file as I did in the second executable line after the function declaration in the Tester class.
• mutants is also attached as a .MAT file.
• tcase has been assigned in the program.
• writeToFile.m is also attached in order to write the cell array into a file.

I cannot find the attachment. Did you use the paper-clip-button of your comment?
