plstat
              Compute statistics of the piecewise linear distribution.
 [m, v] = plstat (x, Fx) returns the mean,
 m, and variance, v, of the piecewise linear distribution with a
 vector of x values at which the CDF changes slope and a vector of CDF
 values Fx that correspond to each value in x.  Both x and
 Fx must be vectors of the same size and at least 2-elements long.
