splitting an array of numbers

I have an array of numbers, for example numbers = rand(1000,1);
I have another array of numbers indicating the offsets for the groups, for example,
offsets = [1, 100, 250, 900, 1000];
so the
first group = numbers(1:100)
second group = numbers(101:250)
third group = numbers(251:900)
fourth group = numbers(901:1000)
I could use a for loop to identify the groups but I want to know if there is a faster way.

numbers = rand(1000,1);
offsets = [0, 100, 250, 900, 1000];
out = mat2cell(numbers,diff(offsets),1);

v=rand(1000,1)
offsets = [0, 100, 250, 900, 1000];
out=arrayfun(@(x) v(offsets(x)+1:offsets(x+1)),1:numel(offsets)-1,'uni',false)
