Adding coordinates to a matrix

[member 428835]

Hi PF!

Given a matrix and vector $$
\begin{bmatrix}
a & b & c\\
d & e & f
\end{bmatrix},\\
\begin{bmatrix}
1\\
2
\end{bmatrix}
$$

how can I merge the two to have something like this

$$
\begin{bmatrix}
(1,a) & (1,b) & (1,c)\\
(2,d) & (2,e) & (2,f)
\end{bmatrix}
$$

Python has tulles and lists of lists that look like matrices. A tuple is basically an ordered collection of different items (123, 456, ‘name’).

What language are you thinking about?

Something like

Table[{B[[k]], A[[k, l]]}, {k, 1, 2}, {l, 1, 3}]

where B and A are your matrices.

The thread tag is "Mathematica".

Okay I didn’t notice that.

Here’s some Mathematica array creation methods.

The last one looks like it constructs something what the OP wants.
