Eigen & TableOfReal: Project...

A command to project the rows of the TableOfReal object onto the eigenspace of the Eigen object.

Setting

Number of dimensions
defines the number of dimensions, i.e., the number of columns, of the resulting object.

Algorithm

Project each row of the TableOfReal on the coordinate system given by the eigenvectors of the Eigen object. This can be done as follows:

yij = Σk=1..numberOfColums ejk xik, where

ejk is the k-th element of the j-th eigenvector, xik is the k-th element of the i-th row and yij is the j-th element at the i-th row of the matrix part of the resulting object.
