Description

Provides the covariant Ricci curvature tensor R_{ij}=R^{s}_{i s j}.

Usage

ricci(g)

Arguments

g	A covariant metric tensor, a "metric_field" object. See metric_field() to create a new metric tensor, or use predefined metrics, e.g. g_eucl_cart().

Value

Returns the covariant Ricci curvature tensor R_{ij} as rank 2 array().
