treams.SphericalWaveBasis.defaultlmax

static SphericalWaveBasis.defaultlmax(dim, nmax=1)

Calculate the default mode order for a given length.

Given the dimension of the T-matrix return the estimated maximal value of l. This is the inverse of defaultdim(). A value of zero is allowed for empty T-matrices.

Example

>>> SphericalWaveBasis.defaultlmax(len(SphericalWaveBasis.default(3)))
3
Parameters:

  • dim (int) – Dimension of the T-matrix, respectively number of modes.

  • nmax (int, optional) – Number of particles, defaults to 1.

Returns:

int
