convert vector to array ; Ex:

Ex:

w = [ 1 2  3 4 5 6 7 8 9 10 11 12 13 14 15 ]

I like to convert it to

g= [1 0 0 0 0 0 0 0 0 0 0 0 0 0 0;
0 2 0 0 0 0 0 0 0 0 0 0 0 0 0 ;
0 0 3 0 0 0 0 0 0 0 0 0 0 0 0;
0 0 0 4 0 0 0 0 0 0 0 0 0 0 0 ;
......until......... ; 
0 0 3 4 5 6 7 8 9 10 11 12 13 14 15;
0 2 3 4 5 6 7 8 9 10 11 12 13 14 15;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15]

that mean I have , rows=2^(2n-1) I got answer from _ the cyclist_ http://www.mathworks.com/matlabcentral/answers/235359-how-can-convert-vector-to- array . it was good answer, but it was active until 5 elements [ 1 2 3 4 5 ]. thank you - the cyclist _
