Hi Lovett,
The view function in MATLAB sets the camera viewpoint for the current figure, but it does not render the 3D object in perspective. To render a 3D object in perspective so that it appears to have depth in a 2D image, you can use the camproj and camva functions to adjust the camera projection and field of view (FOV). Here's an example:
% Generate some random data
x = randn(100,1);
y = randn(100,1);
z = randn(100,1);
% Plot the data as a 3D scatter plot
figure;
scatter3(x,y,z);
% Adjust the view to a projected 2D view from above
camproj('perspective'); % set perspective projection
camup([0 1 0]); % set camera up direction
campos([0 0 max(z)]); % set camera position
camva(30); % set camera view angle
