# 10 Best Free Online Eigenvalues Calculator Websites

Here is a list of the **best free online Eigenvalues Calculator websites**. In linear algebra, “eigen” is a characteristic of a vector that remains unchanged in direction when a transformation is applied. It only only being scaled by an eigenvalue. An eigenvalue is a scalar value that represents the factor by which an eigenvector is scaled during the transformation. It characterizes how the vector’s direction changes but not its direction itself. Calculating eigenvalues is crucial in various fields like physics and engineering as they provide insights into the behavior of linear transformations or systems.

The process of eigenvalue and eigenvector calculation is not easy. Depending on the size of the matrix, it can get more complex. Thankfully, there are calculators that can do this calculation in a matter of seconds. This post covers 10 websites with online eigenvalue calculators that you can use for free. You can simply add your data and run the calculation to get the solution.

## Frequently Asked Questions

An eigenvalue is a scalar value that represents the factor by which an eigenvector (associated with a linear transformation or matrix) is scaled during the transformation. It characterizes how the vector's direction changes but not its direction itself.

An eigenvector is a non-zero vector that remains in the same direction after a linear transformation or matrix operation, only being scaled by an eigenvalue. It represents the inherent structural qualities of a system and helps understand its behavior under transformation.

Eigenvalues are calculated by solving the characteristic equation (det(A - λI) = 0), where A is the matrix, λ represents the eigenvalue, and I is the identity matrix. Solving this equation provides the eigenvalues of the matrix.

Eigenvalues and eigenvectors are found by solving the equation (A - λI)v = 0, where A is the matrix, λ is the eigenvalue, I is the identity matrix, and v is the eigenvector. This equation yields eigenvalues, and plugging them into (A - λI)v = 0 gives the corresponding eigenvectors.

Calculating eigenvalues is crucial in various fields like physics and engineering as they provide insights into the behavior of linear transformations or systems. They help determine stability, vibration modes, and other key characteristics, aiding in solving differential equations and understanding complex phenomena.

The eigenvalues of a matrix are the specific scalar values that, when multiplied by an eigenvector, result in the same vector scaled by a factor. They provide information about how the matrix stretches or compresses space along different directions.

Yes, eigenvalues can be zero. An eigenvalue of zero indicates that the corresponding eigenvector is only subject to translation (no scaling) under the matrix transformation. It's an important scenario in various mathematical and practical contexts.

The term "eigen" comes from the German word "eigen," which translates to "own" or "unique." In the context of linear algebra, "eigen" refers to the characteristic of a vector that remains unchanged in direction, only scaled, when a transformation is applied.
