Welcome to Adams/Solver Subroutines
Rodrigues parameters (R1, R2, and R3) define the relative rotation between two frames of reference. The
relationship between Rodrigues parameters and Euler parameters is R1 = P1/P0, R2 = P2/P0, and
R3 = P3/P0. Rodrigues parameters become undefined when P0 = 0, that is, when the angle of rotation
about the vector is 180 degrees. If the dimension of the string is CHARACTER*12 or longer, the string
can hold any integer defined on a 32-bit machine.
The coord1 and coord2 array length is three, except when the coordinates are in the EULPAR system
(when the array length is four) or in the COSINES system (when the array length is nine). The nine
values of the COSINES system, which forms a three-by-three matrix, are stored in column order in
coord2.
