Function bifurcation draw Bifurcation diagram for multiple stationary points of the map (like logistic map).
MGL code:
subplot 1 1 0 '<_':title 'Bifurcation sample' ranges 0 4 0 1:axis bifurcation 0.005 'x*y*(1-y)' 'r'
C++ code:
void smgl_bifurcation(mglGraph *gr)
{
gr->SubPlot(1,1,0,"<_");
if(big!=3) gr->Title("Bifurcation sample");
gr->SetRanges(0,4,0,1); gr->Axis();
gr->Bifurcation(0.005,"x*y*(1-y)","r");
}
