How to type dots whose slope is 1?

Question

We know how to typeset the commonly used diagonal dots, i.e., \ddots, whose slope is -1.

Now I want to produce dots with slope 1, which is perpendicular to \ddots.

Does anyone know how to do it?

Perhaps the following is a little more general/comprehensive: 3 dots in matrix — Werner, Nov 30 '13 at 00:09

How about using \iddots?

It requires the mathdots package though.

EDIT:

There is a discussion on your problem here

The MnSymbol package provides a \udots macro, which does exactly what you want. When you're looking for some symbol, consult the Comprehensive LaTeX Symbol List; you stand a good chance to find it in there.

enter image description here

\documentclass{article}

\usepackage{amsmath}
\usepackage{MnSymbol}

\begin{document}
\begin{tabular}{ll}
    diagonal dots ($\text{slope} = -1$) & $\ddots$ \\
    diagonal dots ($\text{slope} = 1$)  & $\udots$
\end{tabular}

\end{document}

It depends on tools. If the package graphicx is acceptable, the solution may be as follows

\documentclass{article}

\usepackage[demo]{graphicx}
\begin{document}

\[
A\ddots B \scalebox{-1}[1]{$\ddots$} C
\]

\end{document}

You have to add \mathrel may be... – Nov 30 '13 at 00:11
@HarishKumar Probably yes, but I understand, that OP asks only for a shape, without precising its usage. – Przemysław Scherwentke Nov 30 '13 at 00:15
