From MathWorld --A Wolfram Web Resource. https://mathworld.wolfram.com/MatrixProduct.html The result of a matrix multiplication.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.Matrices in the Wolfram Language are represented as lists of lists. You can use all the standard Wolfram Language list ‐ manipulation operations on matrices. Here is a sample 3 × 3 matrix: In [1]:=. Out [1]=. This picks out the second row of the matrix: In [2]:=. Out [2]=. Here is the second column of the matrix: The . operator is specifically for tensor (including vector and matrix) multiplication. Just multiply without the .: w P + (w^3) P. I can't explain your statement that the product as you have it yields a scalar. For example: P = { {1, 2}, {2, 3}}; w = 5; w.P. Gives the result: 5. { {1, 2}, {2, 3}}; since Mathematica hasn't defined what Dot [a ...Matrix multiplication shares some properties with usual multiplication. However, matrix multiplication is not defined if the number of columns of the first factor differs from the number of rows of the second factor, and it is non-commutative, even when the product remains defined after changing the order of the factors. Of course, matrix multiplication is in general not commutative, so in these block matrix multiplications, it is important to keep the correct order of the multiplications. When the blocks are square matrices, the set of invertible block matrices is a group isomorphic to the general linear group , where is the ring of square matrices .

Strassen in this case does not itself make the algorithm asymptotically faster, but since the bulk of cost is in large integer multiplications one gets a 1/8 speed boost on those parts of the algorithms that use 2x2 matrix products. If memory serves me correctly this gives an overall gain factor somewhere close to 1/8 (maybe 10% or so). Share.A matrix is a concise and useful way of uniquely representing and working with linear transformations.
