Statistics
result = pwpl(xmins, alphas [, x=x] [, random=random])
This function evaluates, or returns samples drawn at random from, a PieceWise Power Law distribution.
Return value
If x is set, the function returns f(x). If random is set, the function returns a set of numbers at random from dN/dx = f(x). f(x) is given by the following equation dN / dx = Const * x^alpha[i], for x[i] <= x < x[i+1] If x < x[0], then dN / dx = 0

TODO: Implement RANDOM keyword
Parameters
- xmins in required
A vector specifying the abscissas of the powerlaw boundaries in increasing order. These are the lower bounds for each piecewise segment.
- alphas in required
The power law exponents at each of the boundaries
Keywords
- x in optional
A set of abscissas against which to evaluate the power law
- random in optional
Set to an integer n to return n samples drawn from this distribution
