I am having a data for example X [56 65 59 98 97 35 54 42].I want to find how many of these data points falls in a given bin range.I also have to generate bin ranges from the data X.
Bin Frequency
  • 50-55 ..... 0 % no data fall in this range
  • 55-60 ..... 3 % three points fall in this range
  • 60-65 ..... 1
  • 65-70 ..... 0.....Please help me how to do this in Matlab?

Edit
X= [56 65 59 98 97 35 54 42];
id=50:5:70
result=histc(X,id)
range=[id(1:end-1)' id(2:end)'];
out=[range result(1:end-1)']

Thank you for your answer.How to create the range (id) directly from data without manually entering id ranges.like id=min(X):5:max(X).Will it work ?

X= [56 65 59 98 97 35 54 42];
a=ceil(X/5)*5
id=min(a):5:max(a)
result=histc(X,id)
range=[id(1:end-1)' id(2:end)'];
out=[range result(1:end-1)']

The histc() function is made for this exact purpose.
