function u = ARTReconstruction(AdrelaxParamnumIterARTu)
% u = ARTReconstruction(AdrelaxParamnumIterARTu)
%
% Algebraic reconstruction technique also known as Kaczmarz method
%
% Inputs:
%
% A = System matrix or Jacobian matrix nr x nc
% = d data nr x 1
% relaxParam = relaxation parameter (between 0 and 1). Choose 0.1 to
% remove noise and 0.9 to get a closer fit of the data
% numIterART = number of iterations
% u = initial guess of the solution image nc x 1. Initialize
% as zeros(nc1)
%
% Outputs:
%
% u = solution image nc x 1
