Hello Everyone,

I feel kind of silly asking this but, after numerous tries and ending up with weird results, I needed to make sure. In order to determine if i'm making a mistake in this step, or some other step of my calculations..

Please refer to this image:Attachment 24400

What i can't be sure of is how to square this vector..

Lets say I have three vectors, each with three members:

Code:

C(1) = {a1,b1,c1}
C(2) = {a2,b2,c2}
C(3) = {a3,b3,c3}

So if I wanted to find 'sd' using the equation in the image. Is this how i should calculate my vectors?

Code:

C(1)^{2} = {a1*a1 , b1*b1 , c1*c1}
C(2)^{2} = {a2*a2 , b2*b2 , c2*c2}
C(3)^{2} = {a3*a3 , b3*b3 , c3*c3}
+
__________________________
sd = { SquareRoot[ (a1*a1 + a2*a2 + a3*a3)/N ] , SquareRoot[ (b1*b1 + b2 * b2 + b3 * b3)/N ] , ... }

I hope I was able to explain myself clearly..

I'd greatly appreciate any help.

Best Regards,

Paul
