    Matrix maths help required!!!

    Can someone please help with the attached document?

    With regards to the attached document, the cell highlighted in yellow,has the following formula:

    =SQRT(MMULT(TRANSPOSE($D$12:$D$20),MMULT($F$12:$N$20,$D$12:$D$20)))

    Can someone please explain how this works, namely the interaction between the two mmult formulae?

    Any assistance will be much appreciated...

    Thanks...
