Abstract : All two dimensional Helmholtz solvers for rectangles at NORDA have been placed in one library with standardized naming and argument list conventions. Each solver has full internal documentation, test software for accuracy, timing and error conditions (such as incorrect dimensions, etc.). The internal documentation for three representative solvers (SMNUUH, SMNSUH and SMMSSH) is reproduced. To invoke a solver, two routines must be called. The first (e.g., CMNUUH) tests the correctness of the arguments and produces constants for use by the solver proper; it need be called only once for each different Helmholtz operation (i.e., it does not depend on the right hand side of the equation). The second (e.g. SMNUUH) when called with the precalculated constants and a right hand side array actually supplies the solution to Helmholtz's equation, it must obviously be called once for each solution required.
