How to do this in Latex?

    Hi everyone,

    I have the following matrix:

    [tex]\begin{pmatrix}
    x_0^{(1)}&x_1^{(1)}&\cdots &x_{N-1}^{(1)}\\
    x_0^{(2)}&x_1^{(2)}&\cdots &x_{N-1}^{(2)}\\
    \vdots &\vdots &\ddots &\vdots\\
    x_0^{(M)}&x_1^{(M)}&\cdots &x_{N-1}^{(M)}
    \end{pmatrix}
    [/tex]

    Now I need to write beside the matrix like [tex]\mathbf{x}^{(1)}=[/tex] on the first row but from outside the matrix, and so on. How can I do that?

    Thanks in advance

    Just on the first row?
    [tex]
    \begin{matrix}
    \mathbf{x}^{(1)} = \\ \phantom{x} \\ \phantom{x} \\ \phantom{x}
    \end{matrix}

    \begin{pmatrix}
    x_0^{(1)}&x_1^{(1)}&\cdots &x_{N-1}^{(1)}\\
    x_0^{(2)}&x_1^{(2)}&\cdots &x_{N-1}^{(2)}\\
    \vdots &\vdots &\ddots &\vdots\\
    x_0^{(M)}&x_1^{(M)}&\cdots &x_{N-1}^{(M)}
    \end{pmatrix}
    [/tex]

    Or every row?


    [tex]
    \begin{matrix}
    \mathbf{x}^{(1)} \\ \mathbf{x}^{(2)} \\ \vdots \\ \mathbf{x}^{(M)}
    \end{matrix}
    =
    \begin{pmatrix}
    x_0^{(1)}&x_1^{(1)}&\cdots &x_{N-1}^{(1)}\\
    x_0^{(2)}&x_1^{(2)}&\cdots &x_{N-1}^{(2)}\\
    \vdots &\vdots &\ddots &\vdots\\
    x_0^{(M)}&x_1^{(M)}&\cdots &x_{N-1}^{(M)}
    \end{pmatrix}
    [/tex]

    Thanks a lot. That is exactly what I wanted. Now I need to do something similar to the columns, and I guess this approach won't work, will it?

    [tex]\begin{matrix}
    \mathbf{x}^{(1)} \\ \mathbf{x}^{(2)} \\ \vdots \\ \mathbf{x}^{(M)}
    \end{matrix}
    =
    \begin{matrix}
    \begin{matrix}
    \mathbf{x_0\ \ }&\mathbf{x_1\ \ }&\ \cdots &\mathbf{x_{N-1}}\\
    \end{matrix}\\
    %
    \begin{pmatrix}
    x_0^{(1)}&x_1^{(1)}&\cdots &x_{N-1}^{(1)}\\
    x_0^{(2)}&x_1^{(2)}&\cdots &x_{N-1}^{(2)}\\
    \vdots &\vdots &\ddots &\vdots\\
    x_0^{(M)}&x_1^{(M)}&\cdots &x_{N-1}^{(M)}
    \end{pmatrix}
    \end{matrix}
    [/tex]
