Yes, the multiplication is different....however, what I see as a 3 row, single column matrix, Mathematica doesn't see it the same way. It treats it the same but I can't define it as I would expect and the software make use of it....so, it doesn't treat them the same way as at least MY mind does.

This Demonstration illustrates how to multiply matrices. You can adjust the dimensions of the matrices.;

The Wolfram Language's matrix operations handle both numeric and symbolic matrices, ... KroneckerProduct — matrix direct product (outer product).

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.

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 …

Times is a function that does multiplication (takes the product) of expressions. The expression Times [ a, b, c, …] is commonly represented using the shorthand syntax a * b * c * …, a × b × c × …, or simply a b c …. Special cases include Times [], which …

Dec 17, 2021 · Matrix Multiplication. The product of two matrices and is defined as. (1) where is summed over for all possible values of and and the notation above uses the Einstein summation convention. The implied summation over repeated indices without the presence of an explicit sum sign is called Einstein summation, and is commonly used in both matrix ...

I totally agree with @InquisitiveInquirer. Multiplication of a (3x1) with a (1x3) matrix should give a (3x3) matrix. I was struggling with this as well. I worked with Mathematica for years, but suddenly I need to switch to Mathlab, because it makes better sense with matrix multiplication.

Frank makes an important point. In Mathematica the dot operator is overloaded, and can be matrix multiplication, matrix-vector multiplication,vector-matrix ...

Different kinds of vector and matrix multiplication. This multiplies each element of the vector by the scalar k:.

8. If you give a matrix with exact symbolic or numerical entries, the Wolfram Language gives the exact inverse. If, on the other hand, some of the entries in your matrix are approximate real numbers, then the Wolfram Language finds an approximate numerical result. Here is a matrix containing approximate real numbers:

Matrices are represented in Mathematica with lists. They can be entered directly with the { } notation that Mathematica provides for lists.

MatrixForm prints SparseArray objects like the corresponding ordinary lists. ». MatrixForm takes the same set of options as TableForm. The typeset form of MatrixForm [ expr] is interpreted the same as expr when used in input. ». When an input evaluates to MatrixForm [ expr], MatrixForm does not appear in the output.
