MATLAB: Convert Column vector into matrix

Question

I have a 1158×1 column vector. The elements of the vector has values from 1 to 256. Each value is repeated for a maximum of 10 times. Some values are repeated even for less than 10 times. I want to convert into 10X256 matrix. I want all the 1's to be in 1st column, 2's in the second column and so on. To make it a proper matrix, fill rest of the values with zeros. The column vector is attached. How can I do that?

Answer 1

H=histcounts(coln,1:257);
result=((1:10).'<=H).*(1:256);
