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 ... I think the fact that Dot is more general than matrix multiplication should be at the start of its documentation, not inside Detail or Possible Issues. For example: "a.b.c or Dot[a,b,c] gives products of vectors, matrices and tensors. Note that Dot works in a more general way than matrix mulitplication.

Example: Let Mmn denote any matrix of m rows and n columns irrespective of contents. We know that MmnMnq works and yields a matrix Mmq. Split A by columns into a block of size a and a block of size b, and do the same with B by rows. Then split A however you wish along its rows, same for B along its columns.

If memory serves me correctly this gives an overall gain factor somewhere close to 1/8 (maybe 10% or so). Share.Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history ...A determinant is a property of a square matrix. The value of the determinant has many implications for the matrix. A determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's ...Inner Product. An inner product is a generalization of the dot product. In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar . More precisely, for a real vector space, an inner product satisfies the following four properties. Let , , and be vectors and be a scalar, then: 1. . 2. . 3. .Matrix Calculator. A matrix, in a mathematical context, is a rectangular array of numbers, symbols, or expressions that are arranged in rows and columns. Matrices are often used in scientific fields such as physics, computer graphics, probability theory, statistics, calculus, numerical analysis, and more. The dimensions of a matrix, A, are ...

Two matrices A and B which satisfy AB=BA (1) under matrix multiplication are said to be commuting. In general, matrix multiplication is not commutative. Furthermore, in general there is no matrix inverse A^ (-1) even when A!=0. Finally, AB can be zero even without A=0 or B=0.box matrix (12) jordan decomposition { {1, 2, 3}, {3, 2, 1}, {1, 2, 3}} LU decomposition { {1, 2, 3}, {3, 2, 1}, {1, 2, 3}} Wolfram|Alpha brings expert-level knowledge and capabilities to …If you’re in the paving industry, you’ve probably heard of stone matrix asphalt (SMA) as an alternative to traditional hot mix asphalt (HMA).
