WebMay 2, 2013 · Since the error is how much the result in this epoch is away from the expected, this should be the right line: error = targets [k]-self.ao [k] But both can be right, it depends on the signal of dsigmoid (self.ao [k]) too. – Arthur Julião May 2, 2013 at 16:20 WebJan 18, 2024 · I'm trying to follow along with the calculation of Fresnel diffraction presented in Siegman's Lasers (1986), page 660. It follows the angular propagation of plane waves in the paraxial approximation. I've gathered that calculating the diffraction pattern formed by an illuminated planar aperture on some other parallel plane is a 3-step process:
