meetpoint

Meet points points and slopes of curves.

Description

Computes the intesection points of curves and the slopes at the meet points.

Syntax:
[X,Y,M0,M1] = MEETPOINT(X0,Y0,X1,Y1)
[X,Y,M0,M1] = MEETPOINT(HANDLES0,HANDLES1)

Outputs:
X,Y Meet points
M1,M2 Slopes

Comments:
Can deal with coincident segments, vertical segments, ...
Works at least in Matlab versions since 5.3 utill current, R14.
Does not use Matlab INTERP1 or any other Matlab interpolation function.

• MATLAB release: MATLAB 6.0 (R12)

It is exactly the function that i was looking for.
Thank you

Dear Sir/Madam,

I am looking for the intersection of dynamic waves and base line. SO far, I could manage to get few of the intersection points using ratio (Y data of dynamic wave/ Y data of base line) for whole of samples. Pls advise me how should I continue since I was stuck in here so long.

I used your function but mine is dynamic wave form and base straing line so the X -axis is not constant line. So the array is only (1900x1) for wave form and base line. The Y values of wave form is changing but the base line is seems like constant. Let say, there is 64 intersection points visuality but what i can get is only 47 but some are not accutare positions.

Thanks and best regards
Kyaw

It did the job it promises.

Hey! Thanks for working on vertical lines, i have some real data sets that contains vertical lines... Would be great if you could implement self intersections.

this is a very useful tool , thanks for your share.ı created cube vertices and faces and patched this .After that I made up a line crossing this cube in two points. And used this tool.Meetpoint showed three same points and missed the point crossed the cube behind. Why is that ?

It does what it says it does. Its documented quite well. Its not terribly fast for large data sets. Error checks are implemented. I wanted to rate it about a 4.5.
