T mean and variance
M = distfun_tstat ( v ) [M,V] = distfun_tstat ( v )
a matrix of doubles, the number of degrees of freedom, v>0.
a matrix of doubles, the mean
a matrix of doubles, the variance
Computes statistics from the T distribution.
The mean of the T distribution is
if v > 1. M is undefined if 0 < v <= 1.
The variance of the T distribution is
if v > 2. We have V=Inf if 1 < v <= 2. V is undefined if 0 < v <= 1.
Any scalar input argument is expanded to a matrix of doubles of the same size as the other input arguments.
