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.

[Walter Roberson]

fprintf(fid, '%s \n',a1{1});

Notice the {} instead of ()

[Matt Tearle]

fprintf(fid, '%s \n',a1{:});

for extra vectorized bonus points :)

Oh i missed that Thank you for the answer.

how can i print it as 'Apple' not just as : Apple

[Matt Tearle]

With the single quote marks actually included, you mean?

fprintf(1, '''%s'' \n',a1{:});

[Rajan]

yea Matt figured it out.thank you for the comments.

You can programmatically interact with the MATLAB Editor using the API introduced in R2011a:

Thank you for the answer.

I am using R2009b.
