543

 
FFT9: a Fortran subroutine for the Dirichlet problem for the Helmholtz equation
on a rectangle. The program is based upon 4th and 6th order accurate 9-point finite
difference approximations and fast Fourier solution techniques. (See E.N.
Houstis and T.S. Papatheodorou, ACM TOMS 5 (1979) pp. 490-493.).
 
Classes  :  I2b1a1a . Poisson (Laplace) or Helmholtz equation on a rectangular
                    domain (or topologically rectangular in the coordinate
                    system)
 
Type     : Fortran software in TOMS collection.
Access   : Some uses prohibited. Portable.
Precision: Single.
