Matrix Calculator

by

MatrixCalc is a fast and simple online tool to perform matrix calculations for learning, homework, and engineering work. Enter values for Matrix A and Matrix B, choose the matrix size (rows × columns), and get results instantly for common matrix operations.

Key Features

  • Two matrices (A & B): Work with both matrices side-by-side.

  • Flexible dimensions: Change rows and columns as needed.

  • Binary operations (A & B):

    • A + B (Addition)

    • A − B and B − A (Subtraction)

    • A × B and B × A (Multiplication)

  • Unary operations (single matrix):

    • Determinant

    • Inverse

    • Transpose

    • Rank

    • Square (A²) (for square matrices)

How to Use

  1. Select the dimensions (rows × columns) for Matrix A and B.

  2. Type your numbers into the matrix cells.

  3. Choose an operation:

    • Use Binary Operations for A & B together (like A×B).

    • Use Unary Operations for one matrix (Active Matrix).

  4. View the result instantly.

Where It Helps (Uses)

  • Students & Teachers: Verify answers, practice linear algebra, and understand matrix rules.

  • Engineering & Science: Solve transformations, systems of equations (with matrix methods), and model real-world problems.

  • Computer Graphics: Use matrix multiplication for 2D/3D transformations (rotate, scale, translate concepts).

  • Data/ML Basics: Matrices are core to linear regression, PCA, and many numerical computations.

Notes

  • Addition/Subtraction: Matrices must be the same size.

  • Multiplication: Columns of the first matrix must match rows of the second.

  • Determinant/Inverse: Only for square matrices; inverse exists only when determinant ≠ 0.
