This function estimates the solution to Kummer's differential equation within a specified tolerance. Kummer's differential equation is given by:

x*g''(x) + (b - x)*g'(x) - a*g(x) = 0

The code executes a while loop to calculate the generalized hypergeometric series within a specified tolerance.

Supports inputs of x in the form of a scalar, row vector, or column vector.

Version Published Release Notes
1.2.0.0

Changed the code to calculate the solution using a while loop to a specified tolerance. The while loop is is both faster and more accurate than the vector multiplication method I was using before.
1.1.0.0

Modified code to be able to handle column vector inputs for x.
