From: hanene chaouch on 7 Jul 2010 06:42 HI!! i have the same problem, i can't found the inverse of CWT in MATLAB. please if you can help me, it's an emergency.

From: hanene chaouch on 13 Jul 2010 07:00 yes i see the message of jo, but his function invcwt works with wavelet.m as a wavelet transform, and the the function that i am looking for is for cwt.m i hope that every body understand me.
