Using functions as input for a function - won't simplify

I've defined a function

P[k_] := 1/[Sqrt]2 (R[k] + L[k])

where R and L generate matrices. However the output of this function never full simplifies (even when I use the Simplify[%] functions). It always leaves the output at 1 over root 2 followed by each of the matrices with the binary operator.

Can anyone tell me what I need to do to simplify this output?

Please post complete minimal code, including definitions for all functions involved. Perhaps explain what you're trying to accomplish. At the very least, the syntax of the Sqrt part looks wonky. – ciao May 02 '14 at 03:16
L[k_] := Table[KroneckerDelta[i + 1, j] Sqrt[i], {i, k}, {j, k}] // MatrixForm – Merry May 02 '14 at 03:18
R[k_] := Table[KroneckerDelta[i, j + 1] Sqrt[j], {i, k}, {j, k}] // MatrixForm – Merry May 02 '14 at 03:18
P[k_] := 1/[Sqrt]2 ((R[k] + L[k]) – Merry May 02 '14 at 03:19
Enclosing the Sqrt in brackets doesn't make much sense – Dr. belisarius May 02 '14 at 03:19
The Sqrt function is correct, for some reason it just changes when I post it here :/ – Merry May 02 '14 at 03:20
So is it Sqrt[2]? In any case drop the //MatrixForm - that is a display form. – ciao May 02 '14 at 03:21
Bleh, that was the problem - thanks for your help! – Merry May 02 '14 at 03:22
