## Help w/ Multiply a List by Scalar then by Another List

(OP)

I need assistance in trying to write the formula on the rule sheet for multiplying a list by a scalar and then be another list.

The actual formula is as follows:

Ao = [Sum(Xi * Aoi^1/2]^1/2

where:

Xi is List1

Aoi is List2

I need to take the square root of Aoi, multiply by Xi, and then and then take the quare root of the sum.

call blank('@temp)

for i = 1 to length('Xi)

'@temp

= 'Xi* sqrt('Aoi)

next i

Ao = sqrt(sum('@temp))

call delete('@temp)

Then list "Ao" as an Output Variable. No Input or Parameter Variables are required.

If you named the function "pfAo" your Rule Sheet would contain the rule: Ao = pfAo()

Let me know if you have any further questions regarding this procedure.
