Detailed Description

This unit test is to verify the accuracy of interpolation method on the function sin(x)/x with a interval of 0.01. sin(x)/x is one of the solution of spherical bessel function when l=0.

• Tested function:
  • 4 types of Polynomial_Interpolation
  • Polynomial_Interpolation_xy
