Hi guys,
I have a somewhat complex question. Simply stated, I have two surfaces, and I want to create a third surface by subtracting one of the two surfaces with the other one. So I want to subtract surfaceA from surfaceB to come up with surfaceC.
But the issue is that surfaceA was created from actual data points, and surfaceB was created from an equation.
How do I create surfaceC given that surfaceA and surfaceB were created differently and are of different type?
Please see my sample code and evaluate my attempt. What do I need to do differently?
Thank you!
Xval = [1 2 3 1 2 3 1 2 3];
Yval = [3 1 2 3 1 2 3 1 2];
Zval = [4 10 5 3 4 6 4 3 2];
xvalue = reshape(Xval,3,3)';
yvalue = reshape(Yval,3,3)';
zvalue = reshape(Zval,3,3)';
figure(1)
surf(xvalue,yvalue,zvalue);
hold off
x = [1:.5:3];
y = [1:.5:3];
Test = @(x,y)x+y;
[X,Y] = meshgrid(x,y);
Z1 = Test(X,Y);
figure(2)
surf(X, Y, Z1);
figure(3)
surf(xvalue,yvalue,zvalue);
hold on
surf(X, Y, Z1);
hold off
