MATLAB: Efficient indexing. Index array generating.

arrayefficientindexingMATLABmatrix
data and array1 are given. I am looking for a more efficient way to generate index. It should be a one-liner.
Thanks in Advance!
  
    data = 1:1000;
    
    array1 = 1:10:101
    array2 = array+2
    
    index = [];
    for i = 1: numel(array1)
        index = [index; array1(i):array2(i)];
    end
    
    data2 = data(index)

Best Answer

data = 1:1000;
array1 = 1:10:101
array1 = 1×11
     1    11    21    31    41    51    61    71    81    91   101

idx = array1(:)+(0:2);
out = data(idx)
out = 11×3
     1     2     3
    11    12    13
    21    22    23
    31    32    33
    41    42    43
    51    52    53
    61    62    63
    71    72    73
    81    82    83
    91    92    93
