I have coding for wavelet edge

j = [1 2 3 4];
s = 2.^j;
teta = wdenoise(y_amp);
teta_f = (1./s).*teta.*(freq./s);
cwt = conv (teta_f, y_amp);

But i have problem with conv which my data is in real not vector. what should i do to fix it

I think you might be trying to say that teta_f is a 2D matrix?

That could happen if theta is a column vector, or a 2d array with as many columns as s has.

Try conv2() instead of conv() if you have 2-D matrices instead of 1-D vectors.
