How can I count the number of elements which are distributed randomly in each region (MATLAB)? -

in work, matlab,i tried distribute n points randomly in circle. divide field in regions (= divided circle segments angle alpha). count number of elements in each regions. know please how count number of elements in each piece of pie??

use polar coordinates point, convert them [theta,roh] = cart2pol(x,y).

roh distrance origin, use a=(roh>2.7)+(roh>5.2) 0 first radios, 1 second , 2 third. theta it's same trick. b=(theta>pi/6)+(theta>pi/3)

now can points a==0&&b==0 small segment next x-axis.
