Function: einstein (<dis>) A function in the
ctensor (component tensor) package.
einstein computes the mixed Einstein tensor after the Christoffel symbols and Ricci tensor have been obtained (with the functions
ricci). If the argument <dis> is
true, then the non-zero values of the mixed Einstein tensor
ein[i,j] will be displayed where
j is the contravariant index. The variable
rateinstein will cause the rational simplification on these components. If
true then the components will also be factored.
There are also some inexact matches for
?? einstein to see them.
