NaN Correlation coefficient

[OBadr]

Using coefficient correlation vi of Labview 2013 for two 1D arrays of zero values, r=NaN.
I don't know why?

[P@Anand · Accepted solution]

When you look into the VI you may see that the final calculation involves dividision of ' r ' by the size of the Y input. So when you leave the Y input empty you will have size 0 which will endup in "Infinity" therotically which is displayed as NaN. Can you show what are the X and Y inputs you are feeding in?

Output of the Get output value VI

[P@Anand]

We don't know what the Get Output value.vi is. Are you new to LabVIEW?

[OBadr]

Sorry, it is Get Output Data vI which get output values of multisim circuit at certain nodes.

You have to probe the X and Y input and check what is the value coming out of the Multisim circuit. I believe the Y may be Zero elements array

[OBadr]

I don't know why it gives array of zeros while the same circuit gives an array of 5 to the same probe but with different file name.

Could you help also how to adjust Get output Data VI for multisim circuit with multi-output probes? And does it work properly?

[P@Anand]

I don't have multisim installed in my PC. Can you take a screen shot of the probe and show us what is happening, also try to attach the VI if possible.
