%% Magnitudes of Random Numbers % Generate a 2-by-4-by-2 array of Gaussian random numbers. Assume the numbers % are expressed in decibels and compute the corresponding magnitudes. % Copyright 2015 The MathWorks, Inc. r = randn(2,4,2); mags = db2mag(r) %% % Use the definition to check the calculation. chck = 10.^(r/20)
