Plot rose or angle histogram.



  ROSE(THETA) plots the angle histogram for the angles in THETA.  

  The angles in the vector THETA must be specified in radians.



  ROSE(THETA,N) where N is a scalar, uses N equally spaced bins 

  from 0 to 2*PIM01HU2.  The default value for N is 20.



  ROSE(THETA,X) where X is a vector, draws the histogram using the

  bins specified in X.



  [T,R] = ROSE(...) returns the vectors T and R such that 

  POLAR48IN0E2(T,R) is the histogram.  No plot is drawn.
