Use this online Matrix Calculator to perform matrix algebra, calculate matrix expressions including complex matrices. You can use this Matrix Calculator to solve simultaneous linear equations system too. Add, subtract, multiply and even divide (multiply by inverse of) compatible matrices. Use this Matrix Calculator to easily calculate the determinant, inverse and adjugate of square matrices and find the rank of a matrix. Also transform matrices to lower triangular, upper triangular and reduced row echelon forms. Full instruction

Note: One interface for all matrices including augmented matrices representing systems of linear equations! The matrix calculator remembers the dimensions and entries of all matrices and whether a matrix is augmented or not. Just select a named matrix from the drop-down list and set its dimensions and fill the matrix with real or complex numbers. You can increase the dimensions of a selected matrix by adding rows or columns to it by pressing the + (insert row or insert column) buttons provided. You can also set the dimensions of a selected matrix by entering the number of its rows or columns in the text boxes provided or, conveniently, by pressing the numbered buttons on the left of a row or above a column, respectively.

Introduction: Matrix Calculator

This elegant matrix calculator deploys one single interface which can be used to enter multiple matrices including augmented matrices representing systems of linear equations!

In addition to adding, multiplying matrices, you can use this matrix calculator to calculate determinant, inverse and adjugate of square matrices and find the rank of any matrix. Also transform matrices to lower triangular, upper triangular and reduced row echelon forms.

You can also solve systems of linear equations. The linear equation solver can solve any m × n linear equations.

Matrices can have real, imaginary and, in general, complex numbers as their elements. This complex matrix calculator can perform matrix algebra, all the previously mentioned matrix operations and solving linear systems with complex matrices too.

Furthermore, this matrix calculator evaluates matrix expressions containing up to eight real or complex matrices and shows work.
