How can I fitting of ksdensity function?

I have vector Z (1*8515 double),I applied ksdensity function on it by the following

[fi,xi] = ksdensity(z,'function','pdf');

My question is how can I fitting of above to extract fitting parameters as the features?

Thanks for all... regards...

I don't think you pass the word 'function' in. And you need to use capital Z because lower case z would be a different variable because MATLAB is case sensitive. Other than that, I don't understand your question. ksdensity() will give you a PDF - essentially a smoothed histogram with an area of 1. What more do you want? What parameters are you talking about?

for example,I calculates histogram by pdf of data and then i want to see or capture theses changes,then I use asymmetric generalize Gaussian distribution model to fitting the curve of histogram. what about kernel density estimate?
