Hi All, this code is supposed to plot a 3D surface and a contour plot of the function with wells at (-2, 2) and (3, -1). However, when I run the code, firstly, the wells are not in the right places, and the dimensions of the axis change as my inputs for x and y change (ie the position of the wells change). What am I doing wrong?
Here is my code,
function M = landscape(x, y)
M = H1(x, y) + H2(x, y);
function h1 = H1(x, y)
R1 = 2;
s1 = [-2;2];
n1 = 2;
h1 = (1./(1+(R1./sqrt((x-s1(1)).^2+(y(:)-s1(2)).^2)).^n1));
end
function h2 = H2(x, y)
R2 = 1;
s2 = [3;-1];
n2 = 1;
h2 = (1./(1+(R2./sqrt((x-s2(1)).^2+(y(:)-s2(2)).^2)).^n2));
end
subplot(1, 2, 1)
surf(M)
subplot(1, 2, 2)
contour(M)
end
And two different graphs the first with x and y -5:5 and the second with x and y -10:10
Notice how the position of the wells change?
