Apologies That's probably what I was looking for. Thanks for your help

I think the issue is that, for reasons I am not smart enough to understand, the computed diffraction pattern is usually different to the...

I haven't tried it because I decided to just use Excel's built-in solver. I subsequently abandoned the project when the solver kept on...

I'm taking the square root so the image looks brighter compare the regular image to the image when the values are squarerooted The...

I'll create a new image with the centre at 0,0 so no shifting is required. Here it is: # fourier_synthesis.py import numpy as np...

I tried it and I get this: Which does have the same general structure as what I'm aiming for, but doesn't "glow" as much Here is the...

So I'm using python to compute the fourier transform of a black and white image and the images I've been getting have been different to...

Not really, but I'll mess around with it as I don't think there is any other reasonable way to solve my problem

It may be easier to express the first two as $$ (1 - sN_i)(1 - c_i \lambda) + sN_i = 1 - c_i\lambda + sc_iN_i \lambda = 0.$$ Newton's...

After some thinking, I don't think this is possible. For an arbitrary stage i, the expression for the mass ratio will be this $$N_i =...

s will be around 0.1. These results make sense but this is a solved issue currently. This is the issue I am currently having

the ##c_i##'s and ##V_f## will be variable but the ##c_i##'s will typically be around ##2400-3000ms^{-1}## and ##V_f## will be anywhere...

This is nice, but @pasmith pointed out a way to make the Jacobian upper triangular, which makes the computation of ##\Delta X_n## much...

So not related to this specific topic but related to this project. So turns out the equations I was working with are likely wrong. So...

Do you mean it's possible to solve the linear system without using Excel's matrix operations each time? If that is correct, I believe...
