multiplying array elements with their indexes

[aksoy]

How can I multiply array elements with their index values.

Thanks in advance.

Hi aksoy,

multiply the elements with their index:

A slightly modified version

Thanks GerdW,

Now I have two arrays. One contains the measurement values and the other has the time for each point. How can I combine these two to have dynamic data with time. Therefore I can filter, graph or write data to a file with time values.

Best regards,

Hi aksoy,

when your data samples are evenly spaced in time you could use a waveform.

But as a generic answer to your generic question I would tend to "stick with your two arrays"!

- You can easily plot them using an XY graph.

- You can easily save them using WriteToSpreadsheetFile.

- You can easily filter them depening on your time array.

- You can easily attach new samples to each array.

You can use the build waveform function to achieve this.

Thanks All,

How can I convert double 2D array to waveform to generate a waveform with time values?

[GerdW]

Hi aksoy,

you can't (easily) convert from 2D array to waveform.

As I mentioned before: when your samples are evenly spaced in time you might convert to a waveform: A waveform consists of start time t0, sample time dt and sample values Y. No need for an additional array with time values here...

If this doesn't apply: stick with two arrays!

Dear GerdW,

I think more or less my problem is clear. I have 2D array with data values. I need it with time values attached to it. Therefore I can play on it easily. Thus I am a new bei in labview. Any suggestions is wellcome.

Hi Aksoy,

given your description I can't give other suggestions as I already did...
