**General Least Squares Linear Fit**VI.Learn how to use the

**Nonlinear Levenberg-Marquardt Fit**VI.Be able to fit a curve to Gaussian (Normal) data points.

In the digital domain, a data set can be represented by two input sequences: *Y Values* and *X Values. A* sample or point in the data set can be written as

(*x*[*i*], *y*[*i*])

where *x*[*i*] is the *i*th element of the sequence *X Values,* and *y*[*i*] is the *i*th element of the sequence ...
