How to compute matrix ^ -0.5

Hi, I would like to know how can I compute a matrix X^-0.5. I know that X^-1 is the inverse so in matlab should it be X^-0.5 or inv(X^0.5) ?

Hi c,
Matlab is short for Matrix Laboratory, and people can just try stuff out and see what happens. It's highly informative to take a small matrix like x = rand(5,5) and compare the results of two expressions above.

And then you can try multiplying the square of the result by X.
