compare and store information of different length into an array

I am taking out information from arrays by doing something like this from a for loop distance(ID == x) , where x = [ 1:9 ]

This gives me data of different lengths.

I want to save all that data in an array and get delta range between all the comparisons with a certain frequency and store that information later to plot a histogram. How do I do that?

Delta range between: column 1 with column 2 3 4 5 6 7 8 9 column 2 with column 1 3 4 5 6 7 8 9 column 3 with column 1 2 4 5 6 7 8 9 column 4 with column 1 2 3 5 6 7 8 9 ... column 9 with column 1 2 3 4 5 6 7 8

Please let me know if more clarification is needed.

Thought: Since I know that the lengths are not the same, I can't store them in an array and I tried to create a matrix with zeros and tried to only store the information of all the arrays in there and I get an error. I think I might be starting this problem wrong.

You can use a cell array: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
