Hello list,

I'm completely new to matplotlib and I'm not a computer scientist (not

a good starting point!) but I need to solve a geometric/graphical

problem.

I've been asked to find a method, in Python, to find the distance

between a 2D polynomial curve, derived from least squares

interpolation on a set of points, and a curve locallly interpolating

another set of points.

- the starting line is a smooth line, while the second should

describe a path passing exactly thorugh the given points.

- the distance should be the one along the normal to the first line

I attach a sketch to explain this.

Is there an heuristic, an algorithm, to solve this problem in an

efficient way (I have to apply it to thousands couples of sets from

sonar and seismic acquisitions)? Is the mapltolip API useful for this?

Thanks in advance,

Giovanni
