InducedFrom

• InducedFrom is an option for DefMetric with form {G, v}, stating that the defined metric is actually the metric G induced on a codimension-1 hypersurface orthogonal to the non-null vector v (with respect to metric G).

• For a non-induced metric the option has the value Null, which is the default.
• See: Section 4.6.
• See also: DefMetric.
• New in version 0.
• Last update: 25-X-2007 for version 0.9.3 of xTensor`.
