fit waveform to equation

[jfazekas]

The polynomial and exponential fit VI's are not adequate for many real-life data fits. How can I fit a waveform to an equation I enter.

For example, fit waveform data to the equation:
y=A*Exp(-b*x)+C*Sin(x)+D*x^2
Where A,b,C,and D are constants to be determined by LabVIEW. x and y are data fit points.
