Convert integer to logical array in MATLAB

Question

I want to convert an integer i to a logical vector with an i-th non-zero element. That can de done with 1:10 == 2, which returns

0              


        

Answer 1

You can use bsxfun:

>> bsxfun(@eq, 1:10, [2 5].')
ans =

   0   1   0   0   0   0   0   0   0   0
   0   0   0   0   1   0   0   0   0   0

Note the transpose .' on the second vector; it's important.
