What is the significance of eigenvalues?

Eigenvalues are the special set of scalar values that is associated with the set of linear equations most probably in the matrix equations. The eigenvectors are also termed as characteristic roots. It is a non-zero vector that can be changed at most by its scalar factor after the application of linear transformations.

What is the use of eigenvalues in daily life?

Eigenvalue analysis is commonly used by oil firms to explore land for oil. Because oil, dirt, and other substances all produce linear systems with varying eigenvalues, eigenvalue analysis can help pinpoint where oil reserves lie.

What is the purpose of eigenvectors?

An eigenvector is a vector that when multiplied with a transformation matrix results in another vector multiplied with a scaler multiple having the same direction as Eigenvector. This scaler multiple is known as Eigenvalue.

What do eigenvalues tell us in population?

Leslie matrices may be used to model the age distribution of a population as well as population growth. The dominant eigenvalue tells us the long term population growth and the corresponding eigenvector tells us the long term age distribution.
