the sum of each row should be 1 and each entry should be 0 or 1 is called 1 of k coding scheme and below are one question solution.
>> C = [1,1,2,3,1,3,2];
>> R = 1:numel(C);
>> A = zeros(numel(C),max(C));
>> A(sub2ind(size(A),R,C)) = 1
A = 1 0 0; 1 0 0; 0 1 0; 0 0 1; 1 0 0; 0 0 1; 0 1 0

So you already have working code? Then what is your question?

C = randi([1,3],2,4)
[m,n] = size(C);
k = max(C(:));
out = zeros(n,k,m);
[ii,kk] = ndgrid(1:m,1:n);
out(sub2ind([n,k,m],kk(:),C(:),ii(:))) = 1

use
C = A + 1;
[m,n] = size(C);
k = max(C(:));
out = zeros(n,k,m);
[ii,kk] = ndgrid(1:m,1:n);
out(sub2ind([n,k,m],kk(:),C(:),ii(:))) = 1;

here this message is showing when i am seeing the value of the out variable.
_ Cannot display summaries of variables with more than 524288 elements._
