Matrix Calculator

Perform basic matrix operations such as addition, subtraction, and scalar multiplication using custom dimensions.

Addition and subtraction require both matrices to have the same size. Scalar multiplication uses only Matrix A.

How it works

Use the same matrix size for A and B, choose an operation, then compute the result. Scalar multiplication applies a number k to every value in Matrix A.

Examples

  • Addition: two 2×2 matrices added entry by entry
  • Subtraction: A − B with matching dimensions
  • Scalar multiplication: k × A multiplies each entry by the same number
