cutline of a triangular meshed graph
1 vue (au cours des 30 derniers jours)
So I was trying to find a cutline at x=0 and want to plot 1D plot along it, so that I can have y vs. z. This is the scatter plot of my graph.
The dots are not arranged meaning that the x and y axis are not the same, they are kinda random, so I tried delaunay function to link all the points together.
But now the question is how do I get the plot at x=0 or any number and plot y vs. z.
Is there a way to do it? I've seen people talking about barycentric coordinates, but I just don't know how to implement it.

The simplest way to do this is to simply interpolate z for a set of points defined by x = 0 and y = the range of your y-data. For example:
x = rand(5000,1)*7 - 3;
y = rand(5000,1)*7 - 3;
z = peaks(x,y);
yi = linspace(-3,3,100);
xi = zeros(1,100);
F = scatteredInterpolant(x,y,z,'linear');
zi = F(xi,yi);
