how to count number of values present in some defined intervals?

Hi, suppose i have a column matrix (:,1). i have to count the number of values lying in the interval say 0-2,2-4,4-6,6-8,8-10. for example say i have a column matrix of values 0.1, 0.2,1,1.9,2.1,2.5,3,4.1,5,5.2,6,8,9.1,9.9. if i have to count the values lying in the given interval how to do it in matlab??? please help

a=[0.1, 0.2,1,1.9,2.1,2.5,3,4.1,5,5.2,6,8,9.1,9.9]
id=[0 2 4 6 8 10]
freq=histc(a,id)

Hi I have also another problem similar to this. Suppose i have m*3 matrix having values of latitude, longitudes and constant number say (0.01,0.5,0.8,1.0,2.5,3.6,5.6,40.0,37.5.....n; 88.9,60.5, 60.6, 87.5, 85.3,99.9, 84.6, 89.5, 90.3, 60.5, 61.3 ....n; 455, 455, 455, 455,............n); the latitude and longitudes values are not ascending or descending, these are scattered values.. if i have to count the count the frequency of the constant number 455 for some interval say for latitude 0-2.5 and longitude 60-62.5, 62.5-65,65-67.5, 67.5-70.....97.5-100 how can i do it sir? please help ...thanks again
