Command: ChnAverage

Calculates the arithmetic means of the single values of several data channels.

Input Parameters

ResultChannel	Specifies the result channel.

Return Parameters

DIAdem calculates the mean rowwise. Each value in the result channel is the arithmetic mean of the values from the same row in all the input channels. The result channel is as long as the shortest input channel.

Examples

The following example calculates linewise the mean value of the channels Group/Channel2 to Group/Channel4.

The following example calculates linewise the mean value of the channels whose names start with the text Channel in the first group of the Data Portal and of all channels in the second group, and saves the result in the Average channel.

Dim oMyChannelList
Set oMyChannelList = Data.GetChannels("[1]/Channel*")
Call oMyChannelList.Add(Data.Root.ChannelGroups(2))
Call ChnAverage(oMyChannelList, "[1]/Average")

oMyChannelList = dd.Data.GetChannels("[1]/Channel*") 
oMyChannelList.Add(dd.Data.Root.ChannelGroups(2)) 
dd.ChnAverage(oMyChannelList, "[1]/Average") 

Dialog Box Call
