Is there a way to efficiently remove the for loop in this assignment?
for jj = length(pple):-1:1
llk(:,:,:,jj) = ll(:,:,:,pple(jj),tple(jj));
endfor
Maybe try
s = size(ll);
s1 = 1:s(1); # etc.
llk( s1,s2,s3, 1:numel(pple) ) =
reshape( ll(s1,s2,s3, pple, tple), [s(1:3), numel(pple)] );
Not tested.
Cheers,
