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

Use makehgtform to translate and rotate the object.
[X,Y,Z]=cylinder([0 3],1000);
M=makehgtform('translate',___,'xrotate',___,'yrotate',___,'zrotate',___);
h=surf(X,Y,Z,'Parent',hgtransform('Matrix',M),___);
ax = gca();
ax.CameraUpVector = [0 1 0];

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;
