How do I rotate the view of a cylinder created using surf plot?

I have created a simple cylinder with radius (r), length (l) and then plotted this to create a surface using the function surf. However, the angle of the plot is such that the cylinder is pointing upwards i.e. z-axis points directly upwards:
I wish to automatically plot the surface but with the orientation change below:
I have attempted to use the view function but can't seem to master this correctly.
Thanks for the help,
Martin

Here is another method, if you want to rotate the surf plot.
figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
xlim([-10 10])
ylim([-10 10])
zlim([0 100])
xlabel('x')
ylabel('y')
zlabel('z')
figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
xlim([-10 10])
ylim([-100 100])
zlim([30 50])
xlabel('x')
ylabel('y')
zlabel('z')
figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
rotate(obj,[0 0 1],90)
xlabel('x')
ylabel('y')
zlabel('z')
xlim([-50 50])
ylim([-10 10])
zlim([30 50])

I must have missed your previous comment.
figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
rotate(obj,[0 0 1],90)
xlabel('z')
ylabel('x')
zlabel('y')
xlim([0 100])
ylim([-10 10])
zlim([-10 20])
obj.XData=obj.XData+50;
obj.YData=obj.YData;
obj.ZData=obj.ZData-40;
