Statistics: tlspdf

### Function Reference: `tlspdf`

statistics: p = tlspdf (x, mu, sigma, df)

Location-scale Student’s T probability density function (PDF).

For each element of x, compute the probability density function (PDF) of the location-scale Student’s T distribution with location parameter mu, scale parameter sigma, and df degrees of freedom. The size of y 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.

### Example: 1

     ## Plot various PDFs from the Student's T distribution
     x = -8:0.01:8;
     y1 = tlspdf (x, 0, 1, 1);
     y2 = tlspdf (x, 0, 2, 2);
     y3 = tlspdf (x, 3, 2, 5);
     y4 = tlspdf (x, -1, 3, Inf);
     plot (x, y1, "-b", x, y2, "-g", x, y3, "-r", x, y4, "-m")
     grid on
     xlim ([-8, 8])
     ylim ([0, 0.41])
     legend ({"mu = 0, sigma = 1, df = 1", "mu = 0, sigma = 2, df = 2", ...
              "mu = 3, sigma = 2, df = 5", 'mu = -1, sigma = 3, df = \infty'}, ...
