design mathematical calculation in script on each element of array.

[H_SH]

Hi all,

I am trying to write the VB script in which i want to do different custom mathematical operation on each element of any specific channel data. For example for every element i want to find average of next two index data and two before and then after based on results, there is further computation.

It will be great help if any one can guide me in performing operation on array elements inside diadem script, as we can do in labview using index in array. There is predefined mathematics and statistics tool in Diadem under analysis tab. But i want to design for my custom mathematical operation.

Thnks

Hi HS,

What version of DIAdem are you using?  The data access functions were improved in the latest DIAdem 11 version.

Hi HS,

Here is a DIAdem 10.2 version of what I understand you to be asking for:

Window = 2

Denom = 2*Window+1

Threshold = 10

ChNum = CNo("[1]/Speed")

FOR i = 1+Window TO ChnLength(ChNum)-Window

  Sum = 0

  FOR j = i-Window TO i+Window

  Sum = Sum + ChDX(j, ChNum)

  NEXT ' j

  Ave = Sum/Denom

  IF Ave > Threshold THEN

    ' do contingent action

  END IF

NEXT ' i
