3. DESCRIPTION OF PROBLEM OR FUNCTION

DOQDP is used to generate direction sets (quadratures used as input to ANISN, DOT, and other related codes). If a fully symmetric quadrature is desired, DOQDP can generate the direction cosines to be used. If other than a fully quadrature is to be generated, the user must supply the appropriate  direction cosines. Once the direction cosines are specified, the code will generate the quadrature weights.

4. METHOD OF SOLUTION

To determine point weights, DOQDP solves a set  of simultaneous linear equations by Gaussian elimination with error  improvement iterations.
