Description

Given an N x N matrix, g a metric with lower indices; and x-, and N-vector (coordinates); EinsteinTensor[g,x] computes the Einstein tensor (an N x N matrix) with lower indices. The demonstration Notebook gives examples dealing with the Schwarzschild solution and the Kerr-Newman metric.
