GradNormalToExtrinsicK

• GradNormalToExtrinsicK[expr, imetric] transforms the derivatives of the normal vector to the induced metric imetric into extrinsick curvature tensors. If the second argument is a list then the function is applied sequentially on all elements.
• GradNormalToExtrinsicK[expr] expands all induced metrics.

• See: Section 4.6.
• See also: ExtrinsicK, ExtrinsicKToGradNormal.
• New in version 0.
• Last update: 25-X-2007 for version 0.9.3 of xTensor`.
