MATLAB: How to map a value of a vector into column number of a matrix

Question

let A=[2;4;5] vector I want a matrix where all the values will be zero and the 2nd 4th and 5th element of column of 10×3 matrix will be 1.

B=[0 0 0
   1 0 0
   0 0 0
   0 1 0
   0 0 1
   0 0 0
   0 0 0

   0 0 0 ]

Answer 1

A = [2, 4, 5];
B      = zeros(10, 3);
idx    = sub2ind(size(B), A, 1:3);
B(idx) = 1;
