Y specifies the array of dependent values, or the observations. The number of input 3.8 Realtime Curve Fitting. This example shows how to do realtime curve fitting in LabView with Origin. It is to demonstrate the following: Connect to a running Origin with OA_ConnectToOrigin.vi which maps to the ApplicationSI method in Origin.

    Edit: My LabVIEW version has a cos fitting VI which is what I am using, the problem is when I try to automate the fitting by changing the initial parameters using a loop, I cant figure out how to get the program to pick the same best fit line as a human would pick. 01/12/2004В В· I was examining the Configuration VI of the Simulate Signal Express VI that ships with LabVIEW.

I am unable to find any documentation to wire the inputs
