acoustotreams.ScalarSphericalWaveBasis.defaultdim

static ScalarSphericalWaveBasis.defaultdim(lmax, nmax=1)

Calculate the number of modes for a given mulipolar degree.

Return the dimesion of the T-matrix given the maximum value of l. This is the inverse of defaultlmax(). A value of lmax=-1 is allowed.

Parameters:

• lmax (int) – Maximum multipolar degree

• nmax (int, optional) – Number of scatterers. Defaults to 1

Returns:

int
