MATLAB: How to make vectors from two points vectors

MATLABmatrix arraymatrix manipulation

In one dimension, I could make a vector interpolates between two points by using ':' operator.
For example:
> index1 = 1;
> index2 = 10;
> vec = [index1:index2]
vec = 
    1    2    3    4    5    6    7    8    9    10
However, I can't make multiple vectors interpolated from the vector of two points.
What should I write in the following '???'.
> index1 = [1; 11, 21];
> index2 = [10; 20; 30];
> vecs = ??? % don't write: [index1(1):index2(1); index1(2):index2(2); index1(3):index2(3)]
vec =
    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

index1 = [1; 11; 21];
index2 = [10; 20; 30];
mat = cell2mat(arrayfun(@(x1,x2)x1:x2,index1,index2,'UniformOutput',false));
