Math equation in latex

hello how can I write this equation in latex?

Best Answer

Here are two ways to typeset the equation in question. The first replicates the expression in the screenshot you posted. The second uses what I would consider to be a somewhat more standard way of expressing the idea that the minimization takes place over an index k that belongs to the set of integers ranging from 1 to n.

\documentclass{article} % or some other suitable document class
\usepackage{amsmath}    % for 'align*' environment
\usepackage{newtxtext,newtxmath} % optional (Times roman fonts)

\begin{document}
\begin{align*}
AB[i,j] &= \min\limits_{k=1}^n (A[i,k]+B[k,j])  \\
AB[i,j] &= \min\limits_{k\in\{1,\dots,n\}} (A[i,k]+B[k,j])
\end{align*}
\end{document}

\documentclass{amsart}


\begin{document}

\begin{equation}
\begin{bmatrix}
 y_1 \\ \vdots \\ y_{34} 
 \end{bmatrix}
 =
 \begin{pmatrix}
  -y_0 && u & u\\
  \vdots && \vdots & \vdots \\
  -y_{33} && u & u
  \end{pmatrix}
  \times
  \begin{pmatrix}
  a \\ b_0 \\ b_1
  \end{pmatrix}
\end{equation}
\end{document}

EDIT:

If you want the type of brackets that Barbara Beeton think you might want, then the following would work.

\documentclass{amsart}


\begin{document}

\begin{equation}
\left\lceil
\begin{array}{c}
 y_1 \\ \vdots \\ y_{34} 
 \end{array}
 \right\rceil
 =
 \begin{pmatrix}
  -y_0 && u & u\\
  \vdots && \vdots & \vdots \\
  -y_{33} && u & u
  \end{pmatrix}
  \times
  \begin{pmatrix}
  a \\ b_0 \\ b_1
  \end{pmatrix}
\end{equation}
\end{document}

Welcome to the site. We will appreciate the questions that have a minimal working example (code) that shows the efforts you have already put. Asking somebody to do things is frowned upon here. If you have no idea of how to start, you may put the following as a MWE

\documentclass{article}
\begin{document}
  %equation here
\end{document}

and ask for the equation code. Since this is your first question, here is the code for the equation you requested and this should get you started.

\documentclass{article}
\usepackage{mathtools}  %% gives more goodies for typing mathematics
\begin{document}
  \begin{equation}
    \hat{b}_k = \frac{2\tau - \Delta_k}{2\tau + \Delta_k}\hat{b}_{k-1} + \frac{\Delta_k}{2\tau + \Delta_k}(b_k + \hat{b}_{k-1})
  \end{equation}
\end{document}
