${\displaystyle f(x,y)=\sin \left({\frac {\pi }{4}}x\right)\sin \left({\frac {\pi }{4}}y\right)}$

${\displaystyle -10\leq x\leq 10~}$, ${\displaystyle -10\leq y\leq 10~}$. Levels ${\displaystyle f(x,y)=-0.1}$ are shown wiht red lines. Levels ${\displaystyle f(x,y)=0.1}$ are shown wiht blue lines. After to generate the eps file, the image was converted to jpg format.

• Contour plot/Code/ado.cin (function that makes header of the eps file)
• Contour plot/Code/conto.cin (function which draws a level)
