function c = decon_cost(X,W) % c = decon_cost(X,W) % Method for seismicdecon example supplied with SA Tools. % See http://www.frostconcepts.com/software for information on SA Tools. % % c = decon_cost(X,W) ; % % X = {K L t f g} % K = length of alpha, tau vectors % L = length of source and detected signals % t = time vector % f = source signal % g = detected signal % W = {alpha tau K} % alpha = attenuation values % tau = translation values % K = length of alpha, tau vectors % c = goodness of fit between W and X % % Calls modelsignal(...) to compute a signal s from alpha and tau given in W. % Computes cost using infinity norm: % c = max(abs(g - s)) % [K,L,t,f,g] = eventparts(X) ; [alpha,tau,K] = modelparts(W) ; s = modelsignal(f,L,alpha,tau,K) ; c = max(abs(g - s)) ;
