# How do I split a vector into parts using indexes?

I have a vector, say
x = 1:100;
and I have a vector that is indexes within the range of the size of x, say,
y=[10,40,60];
I want to cut up x so that I get the three vectors:
x1 = x(1:y(1));
x2 = (y(1)+1:y(2));
x3 = (y(2)+1:y(3));
I tried to use a loop but there is indexing errors due to Matlab indexing starting at 1.
Help appreciated.

x = 1:100;
y = [10,40,60];
C = mat2cell(x(1:y(end)),1,diff([0,y]))
C = 1×3 cell array
{[1 2 3 4 5 6 7 8 9 10]} {[11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40]} {[41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60]}
