WebEigenspace (with Examples) What is Eigenspace? Eigenspace is the span of a set of eigenvectors. These vectors correspond to one eigenvalue. So, an eigenspace always maps to a fixed eigenvalue. It is also a subspace of the original vector space. Finding it is equivalent to calculating eigenvectors. Web16. jún 2024 · A vector’s span is the line that runs through the vector forever. When a vector undergoes a linear transformation (is multiplied by the matrix), usually it is knocked off of its span. However, some types of vectors don’t get knocked off their span. These are the eigenvectors of a matrix.
