Description
Summary
This module creates a N by 9 matrix describing tensors. The tensors are constructed out of two orthogonal N by 3 arrays describing the eigenvectors for the system and 3 column vectors describing the eigen values.
Detailed Description
This module can be used to compute the conductivity tensors of a field, based on the eigen vector decomposition of for instance DTI data. Each of the inputs can be matrix with N rows or with 1 row, in the latter case that value is assumed to be the same for all tensors. The first two inputs are the first two eigen vectors (the third is computed internally using a cross product). These are given as N by 3 arrays, where each row describes a [X,Y,Z] direction vector. The three remaining inputs are the eigen values (or the conductivities ) for the corresponding direction. This can be a scalar value to mark that this value is the same for all or this can be vector with N values, describing an individual value for each tensor. The output is a N by 9 matrix with the tensor entries on the rows of the matrix.
