Adapted from the trirnd(a,c,b,n) user-submited m-file by Dr. Mongkut Piantanakulchai, the tsprnd(a,c,b,n,m) simulates the four-parameter two-sided power distribution with parameters:
a - minimum value
b - maximum value
c - most likely value
n - shape parameter
m - total number of random samples generated, forming an m-by-1 vector X.

A useful alternative to the triangular distribution, allowing for a nonlinear distribution. Triangular and uniform distributions are special cases of the two-sided power distribution.

Details about the two-sided power distribution can be found in:
