HS.py

Dear Sir,

I am using the HS.py to obtain the system Hamiltonian as posted in http://quantumwise.com/forum/index.php?topic=1548.0#.UJt5gWffX1U

however the output i am getting is like

[[ -4.19645437e-02 -4.49943902e-18j  -2.38524478e-18 -7.39248005e-19j

...]

the fact that there's a space between the real and complex numbers

"a +ib"

instead of

"a+ib"

is making it difficult to read for other programs, could you kindly modify the HS.py script accordingly so it writes in a better format?

The output is generated by a simple "print" statement, so it would probably be easier to make a post-processing of the output instead than modify the print statement. Seems to me there are 2 spaces between the numbers and one space within them. So, you could just open the output in a text editor, replace two spaces with some unique character like "&", then remove all spaces, then replace back "&" to a space.
