Question

\begin{algorithm}
\caption{Sinkhorn's algorithm}
\begin{algorithmic}
\WHILE{ $\| B(u_{k}, v_{k})1 - \mu \| + \| B(u_{k}, v_{k})^{T} 1 - \nu \| \ge \epsilon'$ }
    \IF {$k \text{ mod } 2 = 0$}
        \STATE $u_{k+1} = u_{k} + ln \left( \frac{\mu}{B(u_{k},v_{k})\mathrm{1}} \right)$
        \STATE $v_{k+1} = v_{k}$
    \ELSE
        \STATE $v_{k+1} = v_{k} + ln \left( \frac{\nu}{B(u_{k},v_{k})^{T} \mathrm{1}} \right) $
        \STATE $u_{k+1} = u_{k}$
    \ENDIF
        \STATE $k = k+1$
\end{algorithmic}
\end{algorithm}

此代码无效，您知道为什么吗？

感谢和问候。

\ENDWHILE应用于指示循环结束。
