Matrix Calculator

  • System of Equations Calculator
    Solve a 2-variable linear system a₁x+b₁y=c₁, a₂x+b₂y=c₂ instantly using Cramer's rule. Detects parallel/identical lines with no unique solution.
  • Dot Product Calculator
    Calculate the dot product (scalar product) of two 2D or 3D vectors. Also returns each vector's magnitude and the angle between them.
  • Matrix Transpose Calculator
    Enter a matrix as comma-separated values with | for new rows to get its transpose (Aᵀ) instantly. Simple tool for linear algebra and homework.
  • QR Factorization Calculator
    Enter a matrix (use commas for columns and pipes for rows) to compute its QR factorization and get orthogonal Q and upper-triangular R matrices.
  • RREF Matrix Calculator
    Enter a matrix and instantly compute its reduced row echelon form (RREF). Paste values and get the RREF matrix for quick checks and study.
