Eks. på MathML:

ddt[xyz]=[10(y−x)28 x−y−xz−83 z+xy],[xyz]=[−101025],t=0…30 \frac{d}{dt}\left[ \begin{array}{c} x \\ y \\ z \end{array} \right]=\left[ \begin{array}{c} 10\left( y-x \right) \\ 28x-y-xz \\ -\frac{8}{3}z+xy \end{array} \right],\; \left[ \begin{array}{c} x \\ y \\ z \end{array} \right]=\left[ \begin{array}{c} -10 \\ 10 \\ 25 \end{array} \right],\; t=0…30
