Our biggest feat so-far has been fitting a linear function to a set of data by minimizing the least squares differences from the fit to the data with fminsearch. When analyzing non-linear data, you have to use a program like Matlab as many types of data cannot be linearized such that Excel can analyze it.

Matlab can solve these equations approximately with the command c = A \ y. The solution c is called the “least squares” solution for reasons that we will describe later in the course. To illustrate an application involving this use of a rectangular matrix suppose that we wish to fit the three points (0,3), (2,5), and (4,6) with a straight line.

https://info.5y1.org/least-square-fit-matlab_1_fc1574.html
"Polyfit" is a MATLAB function that computes a least squares polynomial for a given set of data. Polyfit actually generates the coefficients of the polynomial (which can be used to simulate a curve to fit the data) according to the degree specified. "Polyval" evaluates a polynomial for a given set of x values.

Least-squares regression. Least-squares regression refers to problems of the form. where is an (n x 1) vector of parameters over which the minimization is performed and xi, wi are the problem data, xi being a scalar and wi an (1 x n) vector, often referred to as the “regressor” vector.
