 I used Octave ver6.3 and did the following:


 >>[t1,r1] = rose( [1:1:360]/180*pi , [0:10:350]/180*pi )
 >>polar(ti,r1) 


and got an uneven rose at about 0. Similar code in matlab produces an even
rose.  Shouldn't we get an even rose in Octave also since the background
distribution is even? 

In my attempt to make a fix I also found that 

[bin_counts]=histc(x,edge_vector)

gave the same length for the bin_counts as for edge_vector. I would expect
length(bin_counts) to be one less than length(edge_vector).
