13.10.2021 · i am doing matrices multiplication in Mathematica 0.12 note book using next code Xo1 = ({ {1, y, 2 x, 2 x y} }).( { {q11}, {q12}, {q13}, {q14} } ); Xo2 = ( { ...
Mathematica apparently doesn't treat matricies in the same way our minds do.... No, this should not become an esoteric topic! A multiplication of numbers and a multiplication of matrices are two totally different things! Here an example:
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.
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 …

Multiplication of matrices (since it involves quite a few more actual numbers than just simple multiplication) is understandably quite a bit more complex. Though the composition of linear functions (as mentioned elsewhere) is the essence of it, that's not the most intuitive description of it (to someone without the abstract algebraic experience).

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.
Multiplying three at once didn't seem to work, so then I decided to multiply the ... It seems that Mathematica is not seeing my [T] matrix as a matrix, ...
In Mathematica the dot operator is overloaded, and can be matrix multiplication, matrix-vector multiplication,vector-matrix multiplication, or the scalar dot product of vectors, depending on context. If possible, Mathematica also conforms the vectors as needed. For example, a nxm matrix can multiply a m-wide row vector without objection. Reply |
Matrix multiplication is also distributive. If and are matrices and and are matrices, then since matrices form Abelian group under addition, matrices form ring. However, matrix multiplication is not, in general, commutative. The product of two block …
04.10.2020 · 5 Answers Active Oldest Votes 2 Although matrix multiplication is not commutative, it is associative in the sense that A ( B C) = ( A B) C for the correct dimensions. To show matrix multiplication is not commutative we can consider an example. Take A = [ 1 1 0 0] B = [ 1 0 0 0] Then A B = [ 1 1 0 0] [ 1 0 0 0] = [ 1 0 0 0] and
