Output parameters

data structure


data_lyon2011(varargin) returns data from rhode1996, lopezpoveda2003, russel1997, ren2002, glasberg1990 and deboer2000 to compare with the results of the lyon2011 model.

The parameter varagin may be one of: rhode1996, lopezpoveda2003, russel1997, ren2002, glasberg1990 or deboer2000. See the references below for the corresponding papers.
