average array

[Qimars]

I am doing FFT for the signal. I would like to average the FFT results of several times, which means adding and dividing them. Now I have got n*5000 points for n times. But how can I add them after I split the original array into serveral 5000 point parts? Thanks!

Hi Qimars,

attached you find an example to get the mean of columns...

Note:
clean up your source! You don't need to insert data into an empty array (lower right corner of main loop)...

Sorry, I only have Windows2000 system and Labview8.20. I cannot open it. Can you just show me a picture?

Hi Qimar,

sorry, here comes the LV8.2 version.

Hello Qimars,

Hi Mike,

here's a simplified version of your example

Btw. I think Qimar want to average lines of data...

Hi Mike and Gerd

You two are so warm-hearted. Thanks a lot!

But what I want to get is also an array, not a number.

2*3 array

1 2

3 4

5 6

what I want is 1*3 array

1.5

3.5

5.5

The first one "MeanOfColumn_LV82" seems right. Because it is (Column+Column....)/N = Column. But it doesn't work if I input some data. So can you give me some further help? My output needs to be one Column which is of tpye array.

Hello again,

ok, here a version with Array output. The other example from GerdW didn´t run because of the empty Array i think.

Hi Qimar,

well, I shouldnt' have used that empty array constant...

Attached version shows calculation for rows and columns...

[Qimars]

Mike,Gerd, I got your idea. But how can I change the input array size?
