I currently have data for 3d points and want to make a matrix out of them
This point data is structured as 3 matrices each containing x, y, z locations which look like these
x=[-3.266573190689087, -3.266134023666382, -3.266134023666382, -3.266573190689087, ... ]
y=[-0.372330516576767, -0.372330516576767, -0.371891230344772, -0.371451914310455, ... ]
z=[-0.085013940930367, -0.085015110671520, -0.084998413920403, -0.085046470165253, ... ]
My hope is to find a way to combine these three matrices into one matrix which would be
matrix( y(i) , x(i) ) = z(i)
x,y,z are all 168136818 long so I dont thick I can share them due to their size
Is there a way to do this in matlab?
thank you for your help.

Let A be your m*3 data matrix.
x = A(:,1) ; y = A(:,2) ; z = A(:,3) ;
%%structured
xi = unique(x) ; yi = unique(y) ;
[X,Y] = meshgrid(xi,yi) ;
Z = reshape(z,size(X)) ;
figure
surf(X,Y,Z)
%%unstructured
dt = delaunayTriangulation(x,y) ;
tri = dt.ConnectivityList ;
figure
trisurf(tri,x,y,z)
