What is Matrix Calculator?

A matrix calculator is an interactive tool that helps you perform a variety of matrix operations such as addition, subtraction, multiplication, determinant, inverse, transpose, and row-reduction. It lets you input your matrices and see calculations instantly, making maths easier.

Students use matrix calculators to simplify their homework, verify answers, and learn step-by-step matrix methods. They are especially handy for checking larger matrix problems quickly and accurately.

Formula Behind Matrix Calculator

Matrix addition adds elements at matching positions, multiplication uses the dot product for each row/column, and the determinant or inverse is computed only for square matrices. For a 2×2 matrix: det(A)=ad−bc, and inverse uses 1/det(A) times the switched and negated elements. Multiplication: (AB)_ij = ∑A_ikB_kj. Transposition switches rows and columns.

Matrix Operation Table

Operation	Example Input	Output
Addition	A = [[1,2],[3,4]], B = [[5,6],[7,8]]	[[6,8],[10,12]]
Subtraction	A = [[9,4],[3,7]], B = [[5,2],[1,1]]	[[4,2],[2,6]]
Multiplication	A = [[1,2],[3,4]], B = [[2,0],[1,2]]	[[4,4],[10,8]]
Determinant	A = [[2,3],[4,5]]	-2
Inverse	A = [[2,5],[1,3]]	[[3,-5],[-1,2]] (÷1)
Transpose	A = [[1,2,3],[4,5,6]]	[[1,4],[2,5],[3,6]]
RREF	A = [[1,2],[2,4]]	[[1,2],[0,0]]
