How to use it

Type a matrix into box A — one row per line, numbers separated by spaces or commas. Box B is a second matrix, or the right-hand-side vector when solving a system. Then press a button.

The buttons

• det determinant · A⁻¹ inverse · Aᵀ transpose (needs a square matrix for det/inverse).
• RREF row-reduces A (paste an augmented matrix here to solve a whole system by hand-method).
• rank the number of independent rows · eigen eigenvalues + eigenvectors.
• A·B multiplies the two matrices · solve Ax=b solves the system using A and vector b.

Example

The defaults solve 2x+y−z=8, −3x−y+2z=−11, −2x+y+2z=−3 → press solve Ax=b to get x=2, y=3, z=−1.

What it can do

All the standard operations · complex eigenvalues · any size that fits on screen · A·B works for any compatible shapes.

What it can't do

Numbers only — no letters or symbols in the matrix. det, inverse and eigen need a square matrix. A·B needs A's column count to equal B's row count, or it errors.
