For example, we have a row vector A
A = [ 4 3 6 2 5];
And I want to convert this row vector into a matrix of '5 X 7' containing zeros and ones only. Required matrix is
% Matrix A
A = [0 0 0 1 0 0 0
0 0 1 0 0 0 0
0 0 0 0 0 1 0
0 1 0 0 0 0 0
0 0 0 0 1 0 0]
Every elment of the row vector represents the position of '1' in each row of the matrix.
Guys, please help me in getting the solution to this problem.

iwant = zeros(length(A),max(A)) ;
for i = 1:length(A)
iwant(i,A(i))=1;
end
