Math & Science ⇒ Random Symbol Replacement in Math Mode

[weezix]

Hi

I seem to be getting a bizarre occurrence in math mode.

Code: Select all

\begin{equation}
  \mathbf{z}(t_{k+1}) = \cal{M}\mathbf{z} (t_{k}) + \boldsymbol{\epsilon}_{m}(t_{k})
\end{equation}

This will display the left hand side of the equation fine, however on the right hand side the 't's are changed to the symbol that normally uses the \sqcup command and the subscripts change to symbols such as these (if I change the subscript letter):
⊣⌊⌋⌈⌉{}|\≀√∐∇∫⊔⊓⊑⊒§†‡ (not all of them copied and pasted here)
The '_m' command becomes the up down arrow \Updownarrow.

The are no errors or warnings when compiling, I have tried remove all the packages but nothing seems to make a difference. In in-line math mode the same thing happens, fine on the LHS, weird behaviour on the RHS. Any ideas?

Please prepare a self-contained and minimal example to avoid guesswork and random shots.

Hi,

welcome to the board!

It's caused by \cal. You could fix it by

• using \mathcal instead
• or enclosing it by braces, such as {\cal z}.

Please follow Thorsten's link to learn why and how to create a minimal example, for the next time, for the best chance to fix a problem.
