I was wondering where does the function value go when fitting a gaussian line. I have a graph and it gives me the equation for that line as well as the coefficient terms (a1, b1, c1, etc.), but it does not give me the overall function value. I have to manually plug in all of the coefficients to find the value. Is there a better way to find this value without having to calculate it by hand (for a gaussian fit)? I appreciate any help.

Help us help you by attaching your data, code, and a screenshot of you plotted data. http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer Are you fitting a histogram, or just random points that look roughly like a normal shape when plotted? Do you have the Statistics and Machine Learning toolbox to take advantage of the functions in there?
