Thanx Honglei

but how i can get Wavelet Toolbox ?

If you are a student then maybe your school may already have it. You can run command ver in your command window and see if you have Wavelet Toolbox available.

Hi Amani,

You asked me a question via email regarding making a GUI. I would suggest you to ask that question in MATLAB Answers. First of all, there are people knows GUI development much better than I do and second, I would rather communicate through this platform than the email.
