Hello,
I intend to generate a 3-D plot in Matlab.
I have 'x' values, and 'y' values in vector format. And corresponding values of dependent function ('z') are in matrix format. Suppose that I do not have the explicit function of 'z' in terms of 'x' and 'y'. I have:
z(x,y) for different values o 'x' and 'y',
(x = 1, 2 and
y = 1.5, 2.25 and
z = [1 3;4 2])
Start with:
x = sort(randn(20, 1)); % Suppose this is given
y = sort(randn(20, 1)); % Suppose this is given
[xx, yy] = meshgrid(x, y);
z = sin(xx) + cos(yy); % Suppose this is given
surf(xx, yy, z);
Then consult https://se.mathworks.com/help/matlab/visualize/creating-3-d-plots.html for more examples.
Have you tried plot3 or scatter3 functions of MATLAB? If I had understood correctly your question, these are the functions you need.
