When you are rotating the figure manually, there will be current azimut and elevation displayed. You need to click the "cube + arrow" icon first.
As my explanation is not the best, I have made screenshot for you to understand easier:
You can write down these numbers and then use them to manually set your desired angle by view(azimut, elevation).
Examples of default angle and edited angle below:
% Default angle
[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
mesh(X,Y,Z)
colormap gray
% Edited angle
[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
mesh(X,Y,Z)
colormap gray
view(-23,28) % setting the azimut and elevation from the numbers
