Averaging Vectors

[ssmith490D]

Are there functions that input a vector, break it down to it's component vectors and back again?? My application involves averaging wind speed and direction. I want to average 60 one second wind vectors by averaging the components and then converting the averaged components back to a single vector of wind speed and direction. Thanks in advance for the help.

Am I understanding your question correctly:
You want to resolve a vector into an x-component and a y-component.

You want to average all the x's, and all the y's, then build them back into a vector?

maybe something like this?

You need first to decide about the repesentation of you vectors. You could make a cluster of the componente, or and array where by index 0 will be the first component, index 1 the second component and so on, or if you stick to 2D you could use complex numbers for the vector representation.

Please find attach an example for averaging 3D-vectors based on the first method a cluster of the components.

Cory--

            That is exactly what I want to do.

I would recommend to combine the two arrays into a complex (CDB) 1D array. The averaged vector is simply Sum/N.

First the single vector must be broken down into it's component vectors and then averaged.

Hi Christian,

I recently had to do some averaging of vectors in three-space and resorted to using complex to do this. As I was doing my code I was thinking "how would Christian have done this?".

Do you have Nuggets of wisdom you could share regarding vectors with more tahn two components.

Curious,

Ben

You can input a vector into this complex array and vector avaeraging will be done correctly??

Hi,

do you think LabView will calc an average incorrectly??

For real:

Many (most basic) functions are polymorph an can take (nearly) any kind of data...
