Package com.metsci.glimpse.util.math.fast

Class Summary
FastAcos  
FastAsin  
FastAtan  
FastErfInverse Approximates the inverse of erf(x), valid on the interval [-0.9999779095,0.9999779095], with a maximum error of about 6e-5.
FastExp  
FastExp2  
FastFunc A function that precomputes its values for speed.
FastFuncUnboundedDomain Provides table look-up capability for functions of bounded range but unbounded domain.
FastGaussian An approximation to a univariate gaussian pdf of mean zero, deviation 1.
FastLog Provides about 12 digits of accuracy at a fraction of the cost of Math.log().
FastLog10  
FastSigmoid  
FastSin  
FastUnscaledGaussian  
PolynomialApprox This class contains polynomial approximations to Trigonometric functions, which are much faster than the Java built-in routines, but not as accurate.
QuickAtan Faster but less accurate than Math.atan.
QuickExp A faster version of Math.exp with maximum relative error of 1e-5.
QuickExp2 Similar to QuickExp but uses 2 smaller lookup tables instead of one large one.
QuickExp3 Similar to QuickExp but uses 3 smaller lookup tables instead of one large one.
