What kind of a favor do you want?
Do you have a question to ask about the following code?
Are you getting the error mesage in your subject line?
At what line of the code do you get the error message?

If tou want help, give us a hint at what you want!

Line 33 change to:

H(c,:) = exp(numerator/denumerator);

instead of:

H(c) = exp(numerator/denumerator);
