Hi there, I have to implement the Kaczmarz-Ansorge program, but they way I make it, I am sure that it is the same as original Kaczmarz.
Basics:
- we take a random value between 1 and M ( this is ik )
- then we make the program on only 1 projection, that random value.
Formula:
Here is what I made, am I on the right path ?
%%%%%Pas 2 Algoritm - K-A %%%%%
% for ik = 1:M
% nlin(ik) = A(ik,:) * A(ik,:)';
% end
%
% for cont = 1:NITER
%
% for jj = 1:M
% ik = M -jj+1;
% x = x - (A(ik,:) * x - b(ik))/nlin(ik) * A(ik,:)';
% end
%
% end
%%%%%End Pas 2 Algoritm - K-A %%%%%
Where NITER are the number of iterations that I have declared in the beginning of program.
Thank you!

My question is if I am on the right path on this. This is about reconstruction of images.
