A matrix is a two-dimensional array of values that is often used to represent a linear transformation or a system of equations. Matrices have many interesting properties and are the core mathematical concept found in linear algebra and are also used in most scientific fields. Matrix algebra, arithmetic and transformations are just a few of the many matrix operations at which Wolfram Alpha excels. Explore various properties of a given matrix. Calculate the trace or the sum of terms on the main diagonal of a matrix. Invert a square invertible matrix or find the pseudoinverse of a non-square matrix. Perform various operations, such as conjugate transposition, on matrices. Find matrix representations for geometric transformations. Add, subtract and multiply vectors and matrices. Calculate the determinant of a square matrix.

KroneckerProduct — matrix direct product outer product.

Hilbert matrices. Explore various properties of a given matrix. Eigensystem — eigenvalues and eigenvectors together. Find matrix representations for geometric transformations. However, matrix multiplication is not , in general, commutative although it is commutative if and are diagonal and of the same dimension. Uh oh! Due to associativity, matrices form a semigroup under multiplication. Give Feedback Top. Wolfram Alpha doesn't run without JavaScript. Please enable JavaScript. If you don't know how, you can find instructions here. MatrixLog — matrix logarithm. Since matrices form an Abelian group under addition, matrices form a ring. MatrixFunction — general matrix function. Matrix algebra, arithmetic and transformations are just a few of the many matrix operations at which Wolfram Alpha excels.
