tlscdf
              "upper")Location-scale Student’s T cumulative distribution function (CDF).
For each element of x, compute the cumulative distribution function (CDF) of the location-scale Student’s T distribution with location parameter mu, scale parameter sigma, and df degrees of freedom. The size of p is the common size of x, mu, sigma, and df. A scalar input functions as a constant matrix of the same size as the other inputs.
 p = tlscdf (x, mu, sigma, df, "upper")
 computes the upper tail probability of the location-scale Student’s T
 distribution with parameters mu, sigma, and df, at the
 values in x.
