create a mathematical function out of samples

[Anonymous]

hello

I'd like to know how can i create a mathematical function out of
samples of a signal (sine wave for example ) .
the samples (around 1000 samples) are known( taken from a text file),
and also the time between every sample is known.

thanks a lot

What you are probably looking for is fitting experimental data to a model function.

LabVIEW has many fitting algorithms built-in and it depends on the desired function to decide what is best. You can fit to a line, polynomial, or exponential, etc., or you can use levenberg-marquardt for more complex models.

If you want to fit to a single sine function, you could use "Extract single tone".

Tell us a little more about your data.
