Solution to a vector to matrix recoding problem

vm-rp

A is 100 dimensional vector containing integers N between [1 and 10] (inclusive) distributed at intervals of 10:
i.e. 
at index x -> N
at index 1 -> 1
at index 11 -> 2
at index 21 -> 3

Problem:
-----------
Need to recode A into a 10x100 (Rows x Columns) matrix such that each column is a 10 dimensional vector y with y(x) = 1 the rest is 0

i.e.
For x between 1 and 10 we will have the same vector (y) replicated 10 times with with y =

111...0
000...1
000...0
000...0
000...0
000...0
000...0
000...0
000...0
000...0

Expected Solution
------------------
I need a vectorized implementation of the above i.e. no for loops and index manipulation, that's easy.

Actual Solution in Matlab/Octave
---------------------------------

x = [1 1 1 2]
A = zeros(10, 4)
A(sub2ind(size(A), x, 1:4)) = 1
