Math & Science ⇒ Problem with creating a matrix

[alpha]

Hello!

I want to create a matrix having one row and multiple columns. I am doing it as follows:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
\usepackage{amsmath}
\begin{equation}
y(k)=
\begin{bmatrix}
a_{0}&a_{1}&a_{2}&b_{1}&b_{2}&c_{1}&c_{2}&d_{1}&d_{2}&e_{1}&e{2} 
\end{bmatrix}
\end{equation}

Run LaTeX here

I am getting the error:

! Extra alignment tab has been changed to \cr.

The matrix currently has 11 columns. If I reduce the columns to 10, the error does not appear.

What can be the reason for this?

Thanks in advance

Hi,

the reason is that amsmath uses 10 array columns internally. You could adjust that by setting the counter MaxMatrixCols:

Code: Select all

1
\setcounter{MaxMatrixCols}{11}
