Hello !

Looking at

Looking at the variable normalizer, I find it to be the same as the denominator in formula 42 of the FASTA field guide:

Now, looking at the variable residual(i) (which, together with variable normalizer makes for the full formula 42 of the FASTA field guide), I fail to understand why it is equal to norm(Dx(:))/tau0 = norm(x1(:) - x0(:))/tau0 and not to norm(gradf0(:) + (x1(:)-x1hat(:))/tau0) ?

Cheers,

Roman

PS: By the way, your FASTA field guide greatly helped me to implement my own twists on FISTA, thanks a lot !

how to conduct when A is FFT or DCT function ?

hi,dear
is there the codes of the papers published in 2008 online ?
could you help me ?
thx
