How can I contruct a matrix with elements set to 1 given by the index position in another matrix?

Hello. I have a a matrix that tells me which of the positions in the other matrix should be set to one. For example-

[2,3,4;3,4,5;1,2,3]

Tells me that I need a matrix like this :

[0 0 1 1 1 0 ; 0 0 0 1 1 1; 0 1 1 1 0 0 ]

How can I obtain this? Thanks in advance

With Loops:

data=[2,3,4;3,4,5;1,2,3]
max_data=max(data(:));
[r c]=size(data);
result=zeros(r,max_data+1)
for i=1:r
    for j=1:c
    data1=data(i,j);
    result(i,data1+1)=1;
    end 
end
result

coloffsets = [2,3,4;3,4,5;1,2,3]

result = zeros(size(coloffsets, 1), 1+max(coloffsets(:)));
result(sub2ind(size(result), repmat((1:size(coloffsets, 1))', 1, size(coloffsets, 2)), 1+coloffsets)) = 1
