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.
