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. See Details and Possible Issues"The word matrix refers to a rectangular array of elements. Matrices have utility in procedures for transforming such sets of elements. For example, one type of procedure would represent the transformation from one set of coordinate axes to another. Another is the solution of linear sets of equations. Common notation for matrices uses a boldface ...The quaternions are members of a noncommutative division algebra first invented by William Rowan Hamilton. The idea for quaternions occurred to him while he was walking along the Royal Canal on his way to a meeting of the Irish Academy, and Hamilton was so pleased with his discovery that he scratched the fundamental formula of quaternion algebra, i^2=j^2=k^2=ijk=-1, (1) into the stone of the ...

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.

Wolfram Demonstrations Project 12,000+ Open Interactive DemonstrationsBlock diagonal matrices, when represented as structured arrays, allow for efficient storage and more efficient operations, including Det, Inverse and LinearSolve.; Block diagonal matrices occur naturally as the adjacency matrices of graphs with multiple connected components, as the tensor product (Kronecker product) of full matrices with diagonal matrices and as the output from Jordan ...matrices multiplication - Wolfram|Alpha. matrices multiplication. Natural Language. Math Input. Extended Keyboard. Examples. Random. Assuming "matrices …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. It is somewhat missing the point to talk about how Dot fails as matrix multiplication. The point of Dot is that it is a tensor operation and that it sometimes corresponds to matrix multiplication. In terms of tensor indices, Dot contracts the right-most index of the first entry with the left-most index of the second.
