I want to a mesh of perpect circle.
But, When I create a mesh it is angled.
How do I get a perfectly round mesh?

With Matlab PDE toolbox it is possible to define a circle and mesh it. You can do it by using the GUI, or by issuing the command pdecirc. For instance:
pdecirc(0, 0, 2); % open the modeler and draw a cirle of center (0,0) and radius 2
The nasty point is that (up to my knowledge) it cannot be done programmatically = pdecirc and similar commands open the modeler.
However, in this way (after meshing) I got this image:
Well, indeed I had to set manually the axis and impose axis to be equal (use the menu Options/Axis limits and Optins/Axis equal), but this is not the point. The point is: why do you need such a mesh, and what do you want to do with it. Do you want to solve a FEM problem?
Concerning mesh generation, perhaps it may be worth to look at DistMesh: http://persson.berkeley.edu/distmesh/
