Approximation for the Tracy-Widom laws
%
% SHIFTED GAMMA APPROXIMATION FOR THE TRACY-WIDOM LAWS, by M. Chiani, 2012
%
% TW ~ Gamma[k,theta]-alpha
%
% [pdf,cdf]=tracywidom_appx(x,2) gives the approximated pdf(x) and CDF(x) of the TW2
%
% [pdf,cdf]=tracywidom_appx(x,i) for i=1,2,4 gives TW1, TW2, TW4

% see paper M.Chiani, "Distribution of the largest eigenvalue for real
% Wishart and Gaussian random matrices and a simple approximation for the
% Tracy-Widom distribution", submitted 2012, ArXiv
