@CameronWilliams Do you not get the inverse via having an indentity matrix beside the matrix you wish to change perform row operations until the left side is the identity matrix (leaving the right side the inverse)?

Add up the square roots of the diagonal?

Oh, when I do take the values, what do I do with them, add them up?

@Amzoti Oh jeeze, It's only the square root of $\Lambda $? Hows does one compute that anyway?

@5xum Updated! It's on diagonalization. Specifically finding the square root of A.

Derp! Thanks pal, I wrote down the formula incorrect and did incorrect gauss-jordan calculations. I'm back on track!

@MarkBennet Indeed! I am however stuck at trying to find $S$ :/, I get a zero matrix from the second eigenvalue.
