Dot@@data should do what you're looking for. It replaces the main Head , List , with Dot , which just multiplies all of the matrices—which used to comprise ...
There's a special command to create a diagonal matrix: DiagonalMatrix[{1, 2, 3}] // MatrixForm. 1 0 0. 0 2 0. 0 0 3. Matrix multiplication is written with a ...
12.01.2022 · The product C of two matrices A and B is defined as c_(ik)=a_(ij)b_(jk), (1) where j is summed over for all possible values of i and k and the notation above uses the Einstein summation convention. The implied summation over repeated indices without the presence of an explicit sum sign is called Einstein summation, and is commonly used in both matrix and …
The Wolfram Language represents matrices and vectors using lists. Anything that is not a list the ... Different kinds of vector and matrix multiplication.
Mathematica multiplies and divides matrices. Mathematica uses two operations for multiplication of matrices: asterisk (*) and dot (.). The asterisk command can be applied only when two matrices have the same dimensions; in this case the output is the matrix containing corresponding products of corresponding entry.
22.02.2015 · I want to product a scalar with a matrix in mathematica. My codes are : w.P + (w^3).P P is a matrix and w is a scalar, but product gives scalar out of the matrix. Why?
Matrix multiplication (also called dot or inner product) is carried out in Mathematica with the function Dot, typically entered with a dot shorthand syntax:.
0. Matrices with doubly-indexed elements The objects of interest to us are ordinary symbolic matrices.

Matrices are represented in the Wolfram Language with lists. They can be entered directly with the { } notation, constructed from a formula, or imported from a data file. The Wolfram Language also has commands for creating diagonal matrices, constant …
The Wolfram Language's matrix operations handle both numeric and symbolic matrices, automatically accessing large numbers of highly efficient algorithms. The Wolfram Language uses state-of-the-art algorithms to work with both dense and sparse matrices, and incorporates a number of powerful original algorithms, especially for high-precision and symbolic matrices.

This tutorial reviews the functions that Mathematica provides for building and working with matrices, vectors, and tensors. It focuses on functions that are specific to Mathematica, and uses matrices for many of the examples. However, all the functions are general, and they will also work for vectors and tensors. Matrices are represented in Mathematica with lists.
