Matrices in Latex

I need to express this as columns

\begin{pmatrix}1\\0\\0\\0\
0\\1\\0\\1\
0\\1\\0\\-1\
3\\0\\5\\1\
0\\0\\0\\0\end{pmatrix}

I've forgotten how to write it in latex, will someone assist me please. Thanks in advance!

I did it by making multiple {pmatrix} environments, one for each column. Feel free to click "quote" on the post where I did this. When setting up your reply, you'll see the LaTeX code I used.

Yes... that gave you individual column vectors... I wanted to augment them into one large matrix. How would you do this?

You do it like this:

\begin{pmatrix}1 & 0 & 0 & 0 \\
0 & 1 & 0 & 1 \\
0 & 1 & 0 & -1\\
3 & 0 & 5 & 1 \\
0 & 0 & 0 & 0 \end{pmatrix}

It produces this:
\(\begin{pmatrix}1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 1 \\ 0 & 1 & 0 & -1\\ 3 & 0 & 5 & 1 \\ 0 & 0 & 0 & 0 \end{pmatrix} \)

although a better way is to use the matrix environment with manual brackets - it produces slightly less crazy brackets:

\left(\begin{matrix}1 & 0 & 0 & 0 \\
0 & 1 & 0 & 1 \\
0 & 1 & 0 & -1\\
3 & 0 & 5 & 1 \\
0 & 0 & 0 & 0 \end{matrix} \right)

\(\left(\begin{matrix}1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 1 \\ 0 & 1 & 0 & -1\\ 3 & 0 & 5 & 1 \\ 0 & 0 & 0 & 0 \end{matrix} \right)\)

 

Oh, I need the row of zero's as a fourth column, it's orientated incorrectly to the way I want it.

 

I forgot to say that what I wrote outputs data in the same order as in the code, ie, rows become rows and columns become columns. A & indicates the next entry in a row while a \\ moves you onto the next line.

 

For instance, I was these

1\\0\\0\\0\
0\\1\\0\\1\
0\\1\\0\\-1\
3\\0\\5\\1\
0\\0\\0\\0\

to be represented vertically, with the 0000 column expressed as the last vertical column.

 

Code:

\begin{pmatrix}
1 & 0 & 0 & 3 & 0\\
0 & 1 & 1 & 0 & 0\\
0 & 0 & 0 & 5 & 0\\
0 & 1 & -1 & 1 & 0\\
\end{pmatrix}

Result: \(\begin{pmatrix} 1 & 0 & 0 & 3 & 0\\ 0 & 1 & 1 & 0 & 0\\ 0 & 0 & 0 & 5 & 0\\ 0 & 1 & -1 & 1 & 0\\ \end{pmatrix}\)

 

Ah, thank you.

 

Are you seriously saying you can't take the transpose of a matrix?!

 

What are you talking about? This is about expressing latex.

 

If by transpose, there is some intimate connection to the name and latex, then yes, I do not know. I've never really studied latex to the degree you have, or possibly even used it to the degree you have.

So yes, it's all very serious.

 

Do you know what the transpose of a matrix is?

 

Who is transposing matrices? I thought this was about using LaTex to display matrices.

\(\begin{pmatrix}A & B \\ C & D & \end{pmatrix} \)

Transpose

\(\begin{pmatrix}A & C \\ B & D & \end{pmatrix} \)

 

GD wrote the columns of a matrix out in rows, and as you know, when you write matrices in latex you need to write rows in rows.

 

Oh right I see what you mean.

 

Next time should ask please put this food in my mouth.

 

Yes, when writing mathematics. This is latex, twit. I don't get you at all.

 

When someone says, you don't know how to transpose, you take that very literally as what it means in real life. I am asking how to write latex, not to transpose.

 

Surely it was obvious that all you needed to do was tranpose the values in your LaTex script.
