Matrix Calculator

Frequently Asked Questions

• What can this matrix calculator solve?

  

  This free matrix calculator helps you solve common linear algebra problems with step-by-step explanations, including determinants, inverses, transposes, eigenvalues, REF, and RREF.

• Is this matrix calculator free?

  

  Yes, it’s completely free to use. You can solve matrix problems online and get step-by-step explanations.

• Can I scan a matrix problem with my camera?

  

  Yes. Use the Socratic AI (ScanMath) app to scan the problem, and it will generate step-by-step solutions automatically.

• What matrix sizes are supported?

  

  Most operations work for common square matrices (like 2×2, 3×3, 4×4). For eigenvalues, determinant, and inverse, the matrix must be square.

• When does a matrix have an inverse?

  

  A matrix is invertible only if its determinant is not zero. If det(a) = 0, the inverse does not exist.
