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. In mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices.

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.Multiplication is the dot product of rows and columns. Rows of the 1st matrix with columns of the 2nd; Example 1. In the above image, 19 in the (0,0) index of the outputted matrix is the dot product of the 1st row of the 1st matrix and the 1st column of the 2nd matrix. Let’s replicate the result in Python.I want to define a product of 3x3 Matrices where the coefficient behave in a different way as usual. I defined the multiplication between coefficient as the function MyScalProd. MyScalProd[x_, y_] := (x^2*y + y^2*x)/2; (*scalar product*) and now I want to use it to multiply coefficients involved in the matrix product. I tried as I could this wayThe Wolfram Language also has commands for creating diagonal matrices, constant matrices, and other special matrix types. A matrix can be entered directly with { } notation: In [1]:=. Out [1]=. You can show the result in matrix notation with MatrixForm: In [2]:=. expr//fun is another way of entering fun [ expr].The second matrix, which contains an integer, is slower for matrix/matrix multiplication. If the operation was something more costly, this difference might not be significant: The cost of mixed numerical matrices comes because Wolfram Language cannot use its efficient storage techniques, as discussed in the section " Packed Arrays ".
