inverse continuous wavelet transform and [Parm] in cwtft what is 'parm' means when you set the name of wavelet function in cwtft or icwtft. wave = {wname,[7.6]}. also can I change Fb and Fc when I use 'morl' function in cwtft or icwtft transform? and If not, then how can I reconstruct my signal with cwt transform? cause cwt let me to select optional value for fb and fc (cmorfb-fc). Matlab doesn't have direct function for inverse wavelet transform.

N = 1024;
t = linspace(0,1,N);
y = sin(2*pi*8*t).*(t&lt;=0.5)+sin(2*pi*16*t).*(t&gt;0.5);
dt = 0.05;s0 = 2*dt;ds = 0.4875;NbSc = 20;
wname = 'morl';sig = {y,dt};sca = {s0,ds,NbSc};
wave = {wname,[7.6]};
cwtsig = cwtft(sig,'scales',sca,'wavelet',wave);
sigrec = icwtft(cwtsig,'signal',sig,'plot');
Why won't cmorwavf work?

Could you then construct a matrix of (complex) Morlet wavelet co-efficients (suitably dilated and translated) and simply invert it for the inverse wavelet transform?
