Hallo everyone,
i have a problem to make the contour plot, it always shows Z must be at least a 2x2 matrix. i have try my best to solve, but it still not work, could you please to help me? The code is as follows.
x=[80;100;90;90;90]
y=[4;4;2;6;4]
[X,Y] = meshgrid(x,y)
% Polly 11 f(x,y)=p00+p10*x+p01*y
f1=1.7419-0.0006*x+0.0132*y
contour(X,Y,f1)
Thanks and best regards
JL

f1=1.7419-0.0006*x+0.0132*y
Fz = scatteredInterpolant(x, y, f1)
F1 = Fz(X,Y)
contour(X,Y,F1)

Your plot is similar to what you would get if you used surfc
