The following codes are freeware. There are absolutely no guarantees.


DATAKING.F Reads a file with two columns, X,F[X], splines the data to a uniform grid, gets the derivative, integrates the data, and outputs all this to a file! This code is very useful. SHOOTAWAY.F Solves the 1 D schroedinger equation using the shooting method. The code can also enforces a delta function boundary condition at the origin. However, I warn you that the algorithm is sufficiently crude that I would not trust numeric results from this code yet. Hopefully, I'll get this up to speed some day.
INVERT.PL Reads a file with lots of rows, places the last row first and first row last, and then, writes all this to a file. Nice and handy, but there's a slight bug; the codes gives an extra carriage return at the head of the output file. D2Q.PL Converts double precision fortran codes to quadruple precision. Note that real*16 is not available on every compile, and if it it is, going to higher precision is not always a good idea. Anyway, this code works fine for smaller codes, but when I apply it to large fortran monsters, it's a little buggy.
