Test Right Hand of tensor
Description
Test Right Hand of tensor
Usage
testrightHAND(U)
Arguments
U
3 by 3 matrix
Details
The fuction eigen does not
always produce a right-handed eigenvector
matrix. The code tests each cross product
to see if it creates a right-hand system.
Value
logical vector

Mtens[2], Mtens[6], Mtens[5],Mtens[6],
Mtens[3]), ncol=3, nrow=3, byrow=TRUE)
E1 <- eigen(M1)
