Guía QuickLaTeX

Guía rápida de QuickLaTeX en WordPress-Editor en una página personal de emm:

Activate QuickLaTeX on a page, post, or comment with the shortcode . Then you may insert LaTeX expressions directly in the text by surrounding them with .. or place them displayed with 


 as you usually do typing offline LaTeX documents.

You may also use display environments equation, align, displaymath, eqnarray, multline, flalign, gather, and alignat.

Here is example of a page with LaTeX formulas (how it appears in WordPress editor):

At first, we sample f(x) in the N (N is odd) equidistant points around x^*:

    \[ f_k = f(x_k),\: x_k = x^*+kh,\: k=-\frac{N-1}{2},\dots,\frac{N-1}{2} \]

where h is some step.
Then we interpolate points \{(x_k,f_k)\} by polynomial

(1)   \begin{equation*}  P_{N-1}(x)=\sum_{j=0}^{N-1}{a_jx^j} \end{equation*}

Its coefficients \{a_j\} are found as a solution of system of linear equations:

(2)   \begin{equation*}  \left\{ P_{N-1}(x_k) = f_k\right\},\quad k=-\frac{N-1}{2},\dots,\frac{N-1}{2} \end{equation*}

Here are references to existing equations: (1), (2).
Here is reference to non-existing equation (??).

QuickLaTeX Example

For the display environments, equation numbering is automatic, but this may be overridden and the number set explicitly with \tag{..} placed within the display expression.

A number of options may be set for an expression with attribute tags such as size, color, background, align, as arguments of \quicklatex{} placed within the expression:


renders with green font of 25 pixels height:


Compilation of an expression may be suppressed, showing instead the LaTeX source, by preceding the expression with a !.

For mathematical graphs you may use tikzpicture and pgfplots, e.g. :
