Math & Science ⇒ a misplaced "="

[NELLLY]

Hi
When I write

Code: Select all

\begin{align*}
\mu^{(0)}=\bordermatrix{&\textit{\small{1}}&\textit{\small{2}}&\textit{\small{3}}&\textit{\small{4}}&\textit{\small{5}}&\textit{\small{6}}\cr
&0&1&0&0&0&0\cr}
\end{align*}
\begin{align*}
\mu^{(1)}&=\mu^{(0)}*P_0^{(1)},\\
\mu^{(1)}&=\bordermatrix{&\textit{\small{1}}&\textit{\small{2}}&\textit{\small{3}}&\textit{\small{4}}&\textit{\small{5}}&\textit{\small{6}}\cr
&a&B&1-a-B&0&0&0\cr}.
\end{align*}

The sign "=" for the second group of formulas is far from "=" of the first formula. What can I do to make them at the same level.
Thanks

Just merge two align* environments to one.

Code: Select all

\begin{align*}
  \mu^{(0)} &=
  \bordermatrix{
    & \textit{\small{1}} & \textit{\small{2}} & \textit{\small{3}} &\textit{\small{4}} & \textit{\small{5}} & \textit{\small{6}}\cr
    & 0 & 1 & 0 & 0 & 0 & 0 \cr
  }\\
  \mu^{(1)} &= \mu^{(0)}*P_0^{(1)},\\
  \mu^{(1)} &=
  \bordermatrix{
    & \textit{\small{1}} & \textit{\small{2}} & \textit{\small{3}} & \textit{\small{4}} & \textit{\small{5}} & \textit{\small{6}}\cr
    & a & B & 1-a-B & 0 & 0 & 0\cr
  }.
\end{align*}

Best regards

Hi
I can't do this because I have a text betwwen them.

Hi,

for the text, you can use the \intertext command provided by amsmath:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
  
\begin{document}

\begin{align*}
  \mu^{(0)} &=
  \bordermatrix{
    & \textit{\small{1}} & \textit{\small{2}} & \textit{\small{3}} &\textit{\small{4}} & \textit{\small{5}} & \textit{\small{6}}\cr
    & 0 & 1 & 0 & 0 & 0 & 0 \cr
  }
  \intertext{some text goes here.}
  \mu^{(1)} &= \mu^{(0)}*P_0^{(1)},\\
  \mu^{(1)} &=
  \bordermatrix{
    & \textit{\small{1}} & \textit{\small{2}} & \textit{\small{3}} & \textit{\small{4}} & \textit{\small{5}} & \textit{\small{6}}\cr
    & a & B & 1-a-B & 0 & 0 & 0\cr
  }.
\end{align*}
\end{document}

If so, then why didn't you provide the complete code right a t the beginning? How should we know what the final result is going to look like? That's what a minimal working example (MWE) is made for.

Thanks this works well. However I have another question. How can I reduce the space between the text in the intertext, the last equation before the text, and the last equation after the text because the space is too large for me.

You can use the optional argument of the \\ command:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
  
\begin{document}

\begin{align*}
  \mu^{(0)} &=
  \bordermatrix{
    & \textit{\small{1}} & \textit{\small{2}} & \textit{\small{3}} &\textit{\small{4}} & \textit{\small{5}} & \textit{\small{6}}\cr
    & 0 & 1 & 0 & 0 & 0 & 0 \cr
  }\\[-4mm]
  \intertext{some text goes here.}\\[-10mm]
  \mu^{(1)} &= \mu^{(0)}*P_0^{(1)},\\
  \mu^{(1)} &=
  \bordermatrix{
    & \textit{\small{1}} & \textit{\small{2}} & \textit{\small{3}} & \textit{\small{4}} & \textit{\small{5}} & \textit{\small{6}}\cr
    & a & B & 1-a-B & 0 & 0 & 0\cr
  }.
\end{align*}
\end{document}

Get used to giving concrete examples for a problem. Nobody is willing to participate in a quiz. You can also try the \shortintertext command provided by the mathtools package from the mh bundle.
