Once selected from the menu this programme will ask for the dimensions of the data set. It requires all three dimensions, eg.

please enter dimensions of the data X Y Z

16 16 16

You will then be prompted to choose whether to type in the gamma matrix (44) element by element, or load it in from a file (default gamma.dat). Your matrix will now be stored in gamma.dat for further use. The gamma matrix is a complex matrix so each element has a real and imaginary part. If an element had a real part of 0.0 and an imaginary part of 1.5 then the user would enter:

( 0.0 , 1.5 ) Return

For example the relevant matrix for the pion ()

(1.0 , 0.0)   (0.0 , 0.0)   (0.0 , 0.0)   (0.0 , 0.0)
(0.0 , 0.0)   (1.0 , 0.0)   (0.0 , 0.0)   (0.0 , 0.0)
(0.0 , 0.0)   (0.0 , 0.0)   (1.0 , 0.0)   (0.0 , 0.0)
(0.0 , 0.0)   (0.0 , 0.0)   (0.0 , 0.0)   (1.0 , 0.0)
