  • $\begingroup$ thank you -- if I'm reading your code right, one of the key elements of your solution is to i) use a discrete fourier transform (not a dct as alluded to in the Rishik reference) and ii) apply equality constraints to the corresponding real and imaginary separately as in this line . $\endgroup$ Commented Sep 24, 2021 at 2:11
  • $\begingroup$ You could use the DCT matrix if you build it as an orthogonal matrix. Since it is a real transform you won’t need to do the trick I did. $\endgroup$ Commented Sep 24, 2021 at 3:27
