About Matrix Calculator

The Matrix Calculator is an online tool that lets you easily perform common linear algebra matrix operations right in your browser. Enter two matrices to compute addition, subtraction, or multiplication, or work with a single matrix to find its transpose, determinant, inverse, trace, or rank.

Supporting 2x2, 3x3, and 4x4 sizes, results appear instantly as you enter values. Ideal for verifying university linear algebra assignments, checking matrix computations in programming projects, or validating preprocessing steps in data science workflows.

Particularly useful, the rank calculation lets you determine the existence and uniqueness of solutions to linear systems. Inverse computation quickly reveals whether a matrix is invertible. All calculations run entirely in your browser — no data is ever sent to a server.

How to use Matrix Calculator

  1. Select the matrix size (2x2, 3x3, or 4x4) from the dropdown
  2. Enter numbers into Matrix A cells. For operations requiring two matrices, also fill in Matrix B
  3. Choose the operation to perform: addition, subtraction, multiplication, transpose, determinant, inverse, trace, rank, or scalar multiplication
  4. Results are displayed automatically below. Decimal precision can be adjusted as needed (trace and rank shown as integers)

Benefits of Matrix Calculator

  • No installation required — complete matrix calculations entirely in your browser
  • Supports 2x2 to 4x4 matrix sizes, covering both study and professional use cases
  • Nine operations (add, subtract, multiply, transpose, determinant, inverse, trace, rank, scalar multiply) in one tool
  • All computations run client-side, ensuring your data stays private
