texvc (TeX validator and converter) is a program which renders mathematical formulae in LaTeX-syntax and outputs graphics that are embedded in wiki articles.

Click on edit to view the LaTeX-syntax in between the math-tag. If texvc is not installed in your Mediawiki-Installation the graphics output is not visible.

Here are some examples of LaTeX output produced in this manner:

• $\int_a^xf(\zeta\,z)\,dx$
• $\int_1^\infty \frac{1}{k^2}\,dk$
• $\sqrt{x^2+2x+1}=|x+1| - ((\frac{2x^2}{x})^2)^2$
• $\ E = \sum_{i=1}^N e^{- J_{ij} \sigma_i \sigma_j}$
• $\ \Phi = \frac{Q}{2\pi}\log(z-z_w)$

Ok. So we had a problem. The math equations were not working yet. They seem to be fine now.

jsMathTest shows how to use jsMath instead. In that case, the above equations become:

• $$\int_a^x f(\alpha\,)\,dx$$
• $$\int_1^\infty \frac{1}{k}\,dk$$
• $$\sqrt{x^2+2x+1}=|x+1| - ((\frac{2x^2}{x})^2)^2$$
• $$\ E = \sum_{i=1}^N e^{- J_{ij} \sigma_i \sigma_j}$$

And here is a comparison of how these two options look for the Cauchy singular integral:

• TeXvc:
$\Omega(z) = \frac{1}{2\pi i}\int_{\Gamma}{\frac{\lambda(\delta)}{z-\delta}d\delta}$
• jsMath: $$\Omega(z) = \frac{1}{2\pi i}\int_{\Gamma}{\frac{\lambda(\delta)}{z-\delta}d\delta}$$
