MATLAB: It doesn’t work out

fftimagetoolbox

I have an image im=imread(…)/255 and If want to take the 2d fft of a color then I use this:

im=im(:,:,1);
im_fft2=fft2;

Now if I want to do it using haart2, matlab won’t let me saying that haart2 requires Wavelet Toolbox. Then it says something like Showaadon(‘WA’,’haart2’). What does it mean? How I’m supposed to use this? I have the newest version R2019a

It means you also need the Wavelet Toolbox.

I assume you played around with the sympref command. Please restore the inital value for typeset outputs with

sympref('TypesetOutput','default');

Please note that any sympref changes are persistent over sessions.

You're asking for the power set of your data. Careful not to use large arrays since the calculation will get out of hand rather quickly.

dataSet = [1 2 3];
n = numel(dataSet);  
%idx = dec2bin(0:2^n-1,n)=='1'; % this is the whole power set
idx = dec2bin(1:2^n-2,n)=='1'; % this is nonempty proper subsets only
S = cell(size(idx,1),1);
for s = 1:size(idx,1),
    S{s} = dataSet(idx(s,:));
end

Hope this helps.
