create a new matrix from
v = [1 1 1 2 2 2 3 3 4];
u=unique(v);
R=arrayfun(@(x)v==u(x),1:numel(u),'un',0);
M=+vertcat(R{:})
what if my matrix is
newV = [1; 1; 1; 2; 2; 2; 3; 3; 4];
what is the change i need to make without transposing the vector newv, to get the output M with newV
i used horzcat, but still without transposing, i'm not able to get result as M

My data was in that form, so, i was asking if i could do it directly.

It works with newV also....you need not to change any part of code.

R=arrayfun(@(x)reshape(newV,1,[])==u(x),1:numel(u),'un',0);
