A command to project the rows of the Matrix object onto the eigenspace of the Eigen object.
Project each row of the Matrix on the coordinate system given by the eigenvectors of the Eigen object. This can be done as follows:
|yij = Σk=1..dimension ejk zik, where|
yij is the j-th element of the i-th row of the result, ejk is the k-th element of the j-th eigenvector, zik is the k-th element of the i-th row of the selected Matrix object, and dimension is the number of elements in an eigenvector.
