Precompute the weights and nodes used in the Gauss-Legendre quadrature based spherical harmonics routines.
zero, w = SHGLQ (lmax)
zero : float, dimension (lmax+1)
: The nodes used in the Gauss-Legendre quadrature over latitude, determined from a call to PreGLQ.
w : float, dimension (lmax+1)
: The weights used in the Gauss-Legendre quadrature over latitude, determined from a call to PreGLQ.
lmax : integer
: The maximum spherical harmonic degree of the coefficients to be calculated in the Gauss-Legendre quadrature based spherical harmonic transform routines.
SHGLQ will calculate the weights and zeros used in the Gauss-Legendre quadrature based spherical harmonic routines SHExpandGLQ, MakeGridGLQ, SHExpandGLQC, and MakeGridGLQC.
