u = [1 -2 -3; -2 4 -7];
v = [-3 2 1; -2 -1 -2];
AB = quiver(u,v);
'AB' draws the elements of the vector 'u' and 'v'
now i want to rotate the angle of each element ( e.g by 10 degrees)
how will i do it ? / what would be the code for it ?
[ i followed this ( http://www.mathworks.nl/matlabcentral/answers/11195-rotating-a-vector) but couldn't work it out. ]
thanks in advance ....

You cannot "rotate an angle". You can rotate a vector around an axis by an angle only. Therefore you have to define the axes of rotation at first. Then the creation of the rotation matrix is not complicated.
