multichannel data separation & finding mean

[VYBH]

Hi

I am having some data in 6 channels. I need to group  them (2 groups each of 3 channels).

After grouping them i need to find mean of each roup.

How can i do the grouping?

Hi VYBH,
build two arrays out of your six channels. Use the "Add Array Elements" function and divide it with the number of elements.

Hi VYBH,

There are many ways to do this depending on the format of the data you have. Here are two examples of manipulating arrays.

What format is your data? Do you have it in an array already or are you reading the data from an NI device?

Hi

I am having USB based cDAQ-9172 alongwith 9219 modules.

I tried my hands using Sort signal option.

I am sorting signals & then adding them to find mean.

Is this right method?

Hi Vaibhav,

I'm not sure I understand what you mean. Can you provide an example of your code that shows how you are calculating the mean?

You should be able to add the signals together and divide by the number of samples.
