Detailed Description

Hold workspace and a few precomputed values for the fast synthesis/analysis.

In normal usage,

• dvect_coef[0/1] holds the even and odd index spherical harmonic coefficients,
• dvect_fcn[0/1] holds the even and odd parity function values in local cosine coordinates,
• eval_fcn[0/1] holds the even and odd parity function values in ordinary coordinates,
• over_rootsin hold 1/sqrt(sin()) at the gaussian nodes,
• mod_weight holds the gaussian quadrature weights times over_rootsine

Field Documentation

int band_limit

The limit on the degree n allowed, used here to specify the memory needed.

Dense_Vector dvect_coef[2]

An array of two Dense_Vectors, of length (band_limit+1)/2 and band_limit/2

Dense_Vector dvect_fcn[2]

An array of two Dense_Vectors, of length (numpts+1)/2 and numpts/2

REAL* eval_fcn[2]

An array of two REAL arrays, of length (numpts+1)/2 and numpts/2

REAL* mod_weight

An array of REALs of length numpts

int numpts

The number of points in the full interval, used here to specify the memory needed and set over_rootin

REAL* over_rootsin

An array of REALs of length numpts
