WebYou can capture the process of doing this in a matrix, and that matrix represents a vector that's called the eigenvector. If the mapping isn't linear, we're out of the realm of the eigenvector and into the realm of the tensor. So eigenvectors do well with linear mappings, but not with nonlinear mappings.
