Compute nodes and weights for quadrature on SO(3). Therefore the following quadrature rules are implemented yet:

'ClenshawCurtis'  - combinate the Gauss quadrature in 1st and 3rd Euler angle
                    (alpha, gamma) with Clenshaw Curtis quadrature in 2nd
                    Euler angle (beta)
'GaussLegendre'   - combinate the Gauss quadrature in 1st and 3rd Euler angle
                    (alpha, gamma) with Gauss Legendre quadrature in 2nd
                    Euler angle (beta)

Syntax

SO3G = quadratureSO3rid(N, 'ClenshawCurtis')
[SO3G, W] = quadratureSO3rid(N,CS,SS,'ClenshawCurtis') % quadrature grid of type Clenshaw Curtis

Input

N bandwidth
CS,SS @symmetries

Output

SO3G orientation grid
W quadrature weights

Options

ClenshawCurtis use Clenshaw Curtis quadrature nodes and weights (default)
GaussLegendre use Gauss Legendre quadrature nodes and weights
