% To run MATLAB ExAO simulations: % The data generation codes were obtain from Curt Vogel. They are set up % for multi-conjugate adaptive optics simulations, but are only used, in % this suite of codes, for standard adaptive optics. % In the first step, set up the necessary atmospheric and astronomical % parameters. >> Setup_params Input number of x-grid points: *** No. of grid points in x-direction = *** Telescope diameter in meters = 8.00 % Then simulate the wavefront and Shack-Hartmann data. >> GenData Enter 1 to reset G operator; else enter 0: 1 Enter 0 for Fried geom or 1 for Hudgin geom: 1 SNR = 100 % There are number of codes in this suite that can be used for the % wavefront estimation step. % Exponential. This was here in the original codes, and I don't know % anything about it. >> SolveExp Exponential Relative Residual Phase Norm = 1.8150e-02 % Least Squares. There are two codes that solve the least squares normal % equations. One uses Gaussian elimination and the other a Cholesky % factorization. The latter is the more efficient. There are implemented % as follows: >> SolveLS >> SolveLSChol % Conjugate Gradient. There are a few preconditioned conjugate gradient % implementations. A multigrid preconditioner is used, the least squares % preconditioner of the paper, and a Fourier preconditioner, which was sent in % the original codes. Also one can implement standard CG. These are done, % respectively, as follows: >> SolveMultiGridPCG >> SolveLaplacianPCG >> SolveFDPCG >> SolveCG % Finally, the method introduced in the paper is implemented as follows: >> Solve
