Hi
How can I split this array so that the 3000s would be in a different array and the 2000s would be in a different one. I know I can just use indexes to do it but I was wondering if there is a general method for it, so that no matter what the values are it would be able to sort it based on the most left handed number(so into 3,2,1) etc.

You can use the function below to find the first digit of positive values, which you can then use to group your data.
f=@(x)floor(x./(10.^floor(log10(x))));
