Sana - the wavedec2 function is part of the Wavelet Toolbox. Check to see if you have this toolbox by typing the following in the Command Window

 ver

If you see the toolbox, then check to see if you have the function by typing

 which wavedec2 -all

If you observe

 'wavedec2' not found.

then you don't have the function.

i didn't find the wavelet toolbox by typing ver. so how could i install it?

You will have to purchase this toolbox.
