Hellooo,
how can i examine if a point in the 2D-Plane is in the convex hull of a quadriliteral, given from 4 points??
I know there is the function "convhull" but this only creates my konvex hull.

You can use the inpolygon() function.

thanks for your hint!!
to be honest, i just don´t get it working^^
would you be so kind as to give me an example for the quadrilateral given by the 4 points
X1=[0,0], X2=[2,0], X3=[2,2] and X4=[0,2]
and one point beeing tested, lets say P=[1,1] ?
