How to convert class cell to vector?

wavelet = ‘db4’;
level = 6;
tt=0:(0.25*10^(-3)):(0.25*10^(-3))*ceil(N);
ref=cos(2*pi*50*tt);
[CR, LR] = wavedec(CurrentwindowR, level, wavelet);
[CY, LY] = wavedec(CurrentwindowY, level, wavelet);
[CB, LB] = wavedec(CurrentwindowB, level, wavelet);
[CRvolt, LRvolt] = wavedec(VoltagewindowR, level, wavelet);
[CYvolt, LYvolt] = wavedec(VoltagewindowY, level, wavelet);
[CBvolt, LBvolt] = wavedec(VoltagewindowB, level, wavelet);
[Cref, Lref] = wavedec(ref, level, wavelet);
