To plot 3 vectors A,B & C, I have used surf plot. I have noticed there is a syntax error in my code below. When I select the columns from the variables and used the plots on the Menu bar...the surface plot popped up but the axis limits are not matching with my data? I appreciate your suggestions.

A=data(1:78,1); B=data(1:78,2); C=data(1:78,3); surf(A,B,C)

在 MATLAB Online 中打开

data = importdata('data.txt') ;
x = data(:,1) ; y = data(:,2) ; z = data(:,3) ;
dt = delaunayTriangulation(x,y) ;
tri = dt.ConnectivityList ;
xi = dt.Points(:,1) ; 
yi = dt.Points(:,2) ; 
F = scatteredInterpolant(x,y,z);
zi = F(xi,yi) ;
trisurf(tri,xi,yi,zi)
