This is not complicated:
FID = fopen(fullfile(tempdir, 'MyFunction.m'));
if FID < 0, error('Cannot open file'); end
fprintf(FID, 'function out = MyFunction(in)\n');
fprintf(FID, 'disp(in);\n');
fprintf(FID, 'out = clock;\n');
fclose(FID)
But creating M-files dynamically is a critical task. Are you really sure, that this is an efficient method to solve your problem?

Thank you for reply Jan Simon.
I get a error saying:Function is not defined for 'cell' inputs.
when i run this:
a1={'Apple','Ball','cat','Dog'};
fid = fopen('created.m', 'w');
fprintf(fid, 'Alphabets\n');
fprintf(fid, '%s \n',a1(1)); %This line is giving the error %
fclose(fid);
type created.m
How can i print all the elements in a1 in my mfile.

fprintf(fid, '%s \n',a1{1});
Notice the {} instead of ()

fprintf(fid, '%s \n',a1{:});
for extra vectorized bonus points :)

With the single quote marks actually included, you mean?
fprintf(1, '''%s'' \n',a1{:});
