conatus.expert.MappedChebyshev

class conatus.expert.MappedChebyshev(coord, size, map, dealias=REQUIRED, grid='floor')

Bases: Chebyshev

Chebyshev T_n(xi) with a declared map y = m(xi) onto an (semi-)infinite interval.

bounds are the physical ones (e.g. (-inf, inf)); the collocation grid is m(xi_j) at the Gauss–Chebyshev points xi_j. Supported by the discretizer (EVP, LBVP, NLBVP) and the reference evaluator; refused by the time steppers and by symmetry subspaces (explicitly).

Parameters:

• coord (Coordinate)

• size (int)

• map (CoordinateMap)

• dealias (Any)

• grid (str)

family = 'Chebyshev T in a mapped coordinate'
