how to write a very concise expression for matrix power

I have a row vector, e.g. [1,2,3,4], and I want to put, say 3 different power [1;2;3] to create a matrix as follow:

[1,2,3,4]?^[1;2;3] = [1,2,3,4 ; 1,4,9,16 ; 1,8,27,64].

Anyone knows how to get it without using a loop. Many thanks!

As of R2016b, you can just do this

[1;2;3] .^ [1,2,3,4]

Otherwise, use bsxfun()

Ahh, I am using 2011, didn't know it works in 2016.

Thanks for reply. Is there any other way to let it work.

Upgrade!

Or, use bsxfun() as I suggested.

Nice, bsxfun does work. Thank you so much!

>> bsxfun(@power,[1:4],[1:3].')
ans =
   1     2     3     4
   1     4     9    16
   1     8    27    64
