conatus.expert.Chebyshev

class conatus.expert.Chebyshev(coord, size, bounds, dealias=REQUIRED, grid='floor')[source]

Bases: Jacobi

Chebyshev T_n = Jacobi(-1/2, -1/2) up to normalisation.

Parameters:

  • coord (Coordinate)

  • size (int)

  • bounds (tuple[float, float])

  • dealias (Any)

  • grid (str)

family = 'Chebyshev T (Jacobi -1/2,-1/2)'
