MATLAB: Columnwise power operation in matrix

Question

Hi everyone (first post here)!

Say I have a vector x = [1;2;3].

I would like to construct a matrix X, where every column is the vector x raised to the power of the column number:

      1  1  1  
  X = 2  4  8
      3  9 27

With a for-loop, this is easily done:

for i=1:3
  X(:,i) = x.^i;
end

But could this be done with vector operation instead of using a for loop?

Answer 1

bsxfun( @power, x, 1:3 )
