Split data into groups

Hi,

How can I split data into 3 groups? For example, if I have 300 values, I want 100 lowest values in 1 group, 100 highest values in 1 group and the in-between values in another group.

Thank you

A = randi(5000,300,1); % random data
A = sortrows(A); % sort it
low = A(1:100); % just use indexing now
mid = A(101:200);
high = A(201:300);
