1. The Ezyfit toolbox for Matlab enables you to perform simple curve fitting of one-dimensional data using arbitrary (non linear) fitting functions. EzyFit adds a new menu to your figure windows, which allows you to easily fit your data with predefined or user-defined fit equations, including selection of your data (outliers removing) using the ``Data Brushing'' tool
2. Curve Fitting in Matlab. Matlab has two functions, polyfit and polyval, which can quickly and easily fit a set of data points with a polynomial. The equation for a polynomial line is: Here, the coefficients are the a0, a1, and so on. If you had a straight line, then n=1, and the equation would be: f(x) = a0x + a
3. Curve Fitting. Often we need to find out the best line of fit that passes through a given set of points, or we want to generate a curve that best represents a data. Using MATLAB, we can generate that best line of fit, and this process is known as curve fitting
