The food pellets also have color additives that help give the farm raised salmon the nice pinkish color weâre all accustomed to. Otherwise, theyâd be a dullish grey color*. *Wild salmon, by contrast, obtain their pink hue from their natural environment by feasting on a diet of krill, which eats red algae. 7.
Generate random numbers with a given distribution. The rand function in MATLAB returns uniformly distributed pseudorandom values from the open interval (0, 1), but we often need random numbers of other kind of distributions. A great article written by John S. Denker explains a method of generating random numbers with arbitrary distribution.
Standard deviation of Matlab 'randn' function. up vote 1 down vote favorite. A quick and simple check (using code in MATLAB) shows that the numbers generated by MATLAB's randn function have a standard deviation that is one-fifth of the peak-peak variation. MATLAB CODE: randn('state',0); rn = randn(100,1); (max(rn)-min(rn))/std(rn).
