ROI wavelet coefficients
Hello, I would like to ask you how to obtain the wavelet coefficients of a specific region(x:xmax,y:ymax) of the image. I would do it by cH(x/2^level: xmax/2^level, y/2^level:ymax/2^level) but as is stated in the wavelet toolbox guide "the actual lengths of the detail and approximation coefficient vectors are sl... 21 Jun 2010 06:56

Using plotyy to plot several series
I am trying to use plotyy to four series three of which have the same y-axis, the fourth has a different y-axis. So far my code looks something like this: X1=[x1 x2 x3]; Y1=[y1 y2 y3]; plotyy(X1,Y1,x4,y4) I do get a plot but I am not to satisified with the result. First, I would like to set the line type for each... 21 Jun 2010 09:07

Dear all, I don't manage to get a 4D array from a serie of 3D arrays that underwent the same function? I mean: a=arrayfun(@(i) fun(V.i), 1:n) the output is an error, unless i add UniformOutput false at the end. but the result is a cell array in this case. while i want a normal array instead. since i have to repea... 21 Jun 2010 08:01
