uricci

Maxima Function

Calling Sequence

uricci (dis)

Description

This function first computes the covariant components ric[i,j] of the Ricci tensor. Then the mixed Ricci tensor is computed using the contravariant metric tensor. If the value of the argument dis is true, then these mixed components, uric[i,j] (the index i is covariant and the index j is contravariant), will be displayed directly. Otherwise, ricci(false) will simply compute the entries of the array uric[i,j] without displaying the results.
