31.08.2014 22:45:22 [INFO ] [Plugin.Initialize()] mwbeta(2) - (Z,W) computes the beta function for corresponding elements of Z and W. The beta function is defined as beta(z,w) = integral from 0 to 1 of t.^(z-1) .* (1-t).^(w-1) dt. The arrays Z and W must be the same size (or either can be scalar).
31.08.2014 22:45:22 [INFO ] [Plugin.Initialize()] mwbetainc(3) - (X,Z,W) computes the incomplete beta function for corresponding elements of X, Z, and W. The elements of X must be in the closed interval [0,1]. The arguments X, Z and W must all be the same size (or any of them can be scalar).
31.08.2014 22:45:22 [INFO ] [Plugin.Initialize()] mwbetaln(2) - (Z,W) computes the natural logarithm of the beta function for corresponding elements of Z and W. The arrays Z and W must be the same size (or either can be scalar). BETALN is defined as: BETALN = LOG(BETA(Z,W)) and is obtained without computing BETA(Z,W). Since the beta function can range over very large or very small values, its logarithm is sometimes more useful
