test_int_circle


test_int_circle, a Fortran77 code which defines several test integrals over the unit circle, making it possible to check the accuracy of quadrature rules.

Currently, the test integrals include:

  1. x^e, where the parameter e is set by the user.
  2. r^e, where the parameter e is set by the user.
  3. exp(x)
