Great GPU application to show how your GPU compares to others.

Hi, looking at your code again I noticed that in calculating psiNorm in line 168 in: "calculateHydrogenicWavefunction.m" you are missing a power of 3 over factorial(N+L), that is according to :introductory quantum mechanics" by Liboff, table 10.3

Hi, thanks for this contribution.
I am also using Hydrogen eigenfunction \psi=Ylm(\theta,\phi)*Rnl(r) and encountered a problem which I detect in this tool as well, regarding the file: "calculateHydrogenicWavefunction.m". It appears that your wavefunctions are not orthonormal... for example the inner-product of the wavefunctions for (N,L,M)=(2,1,0) and (3,1,0) does not vanish.
If psi1 is the matrix for (2,1,0) and psi2 is for (3,1,0) then sum(sum(sum(psi1*conj(psi2)))) is -2.7754. I suspect it has something to do with the implementation of the radial functions.
Is this a numerical by product? How can this be avoided?

Thanks a lot!
Oren

Great complement to dctool.
