Complex pointer drawing function

--

How to use

• download the draw_functions
• additionaly, download auxiliary functions here!
• add them to our working directory
• use them like this

U12=complex_angled(400,0);
U23=complex_angled(400,-120);
U31=complex_angled(400,-240);

Z1=10+i*17.32;
Z2=0+40*i;
