Matrix Calculator: The Complete Guide

Analyse a matrix in seconds. Enter your matrix one row per line to see its dimensions, its determinant (for square matrices), and its transpose.

Who the Matrix Calculator is for

Students and engineers needing quick matrix properties without specialised software.

How to use the Matrix Calculator

  1. Type your values into the fields above — pick your currency or units where the calculator offers them.
  2. Results update automatically as you type; there's no submit button and nothing is sent to a server.
  3. Adjust any input to compare scenarios, then copy the result with a single click.

How it works

The determinant is computed by cofactor expansion for square matrices. The transpose swaps rows and columns, turning an m × n matrix into an n × m one.

Features

  • Matrix dimensions
  • Determinant (square)
  • Transpose
  • Any size

Determinant and transpose

The determinant is a single number summarising a square matrix — zero means the matrix is singular (non-invertible). The transpose flips a matrix across its diagonal, swapping rows and columns. Both are fundamental in linear algebra, graphics, and solving systems of equations.

Frequently Asked Questions

How do I enter a matrix?

Type each row on its own line, with the numbers separated by spaces or commas. All rows must have the same number of columns.

Why is the determinant only shown for some matrices?

Determinants are defined only for square matrices (same number of rows and columns). Rectangular matrices still show dimensions and a transpose.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
