test_interp

test_interp(float64_tols, method, nsteps, quad_problem, fun_type)

Tests the accuracy of barycentric Lagrange interpolation.

Parameters:

• method (str) – [‘Gauss’, ‘Radau_I’, ‘Radau_II’, ‘Lobatto_III’, ‘Cheb_I’, ‘Cheb_II’, ‘ClenshawCurtis’]

• nsteps (int) – [25, 50, 100]

• quad_problem (dict) – [‘Wallis’]

• fun_type (str) – [‘py_fun’, ‘c_fun_memoryview’, ‘c_fun_pointer’]
