What Are Singular Values?

Singular values measure how a matrix stretches space in different directions.

How To Use The Singular Values Calculator

  1. Enter the four entries of the 2x2 matrix.
  2. Review the values in the result panel.
  3. Use the steps section to see the matrix workflow.

Worked Example

For the matrix [[1, 2], [3, 4]], the calculator returns the two singular values.

Singular values come from sqrt(eigenvalues of A^T A)
The result panel shows both values to six decimals

Frequently Asked Questions

Why are singular values important?

They are used in stability checks, compression, and many linear algebra workflows.

Why only 2x2 matrices?

This version is scoped to a 2x2 matrix so the calculator stays simple and fast.
