flag if plot Intersects itself
显示 更早的评论
I have an array of size n by 2 where column one has the x coordinates whilst column 2 has the y coordinates. I plan to plot these coordinates but I wanted to know if there is an easy way to know if this plot is going to intersect itself across the range of points n without manually plotting and observing the resuly.

No, there are ways but no easy ways.
Plotting is not robust enough to determine this, as the distance between lines might be less than the width of a pixel.
