Some reference




@Markiyan Hirny 

minkowski space is 4 dimensional Space.

The equation of Motion arme The geodetic line, you can calculate the equations with the metric and the chistofel symbols, but I am using different approach. Of course the result are the same.

I hope I could answer your quastion?

@John Fredsted 

o.k this is what I need perfect!


for Einstein Tensor

thank you


again, G is not the metric (input)! G is the output !



the results are table ,so how can I  can convert it to array? (Matrix) ?.

Thus is what I need

for example G is a 4x4 Matrix




what i meant is:

Everything works perfect.

The result that I get is file list.

I need it into array, let say G[4,4] for the result of Einstein field.

The program doesn't provide it?
