Fit a curve to data and determining goodness of fit. Use the function fminsearch in MATLAB to minimize a function. Understand vocabulary used to describe model fits to data. Use simple theory about model fitting to select the best model for a data set. Definitions: Polynomial: A polynomial is of the form. f(x) = a. n. x. n + a. n-1. x. n-1 ...

The same values for the parameters can also be obtained by using polyfit, a function provided by Matlab, to find the best linear fit of the data. % Matlab program for Example 5.1-1 % Least square curve fitting of ln(Ca) = ln(Cao) - kt

So when you’re fitting data with normally distributed errors, you can analyze the errors to the fits with the variance-covariance matrix method which I am still waiting for most of you to do. Abnormal Errors. Now let’s look at this exponential decay curve: Figure 3. Here is a histogram of the errorbars: Figure 4

If you don’t have the Curve Fitting Toolbox installed a linear fit will be displayed, by default. XY: This window now has two plots: (1) the X and Y data points and (2) the plot of the residual or the difference between the data points and the line fitted through them.

Curve Fitting with MATLAB Curve fitting is a useful tool for representing a data set in a linear or quadratic fashion. MATLAB has two functions, polyfit and polyval, which can quickly and easily fit a polynimial to a set of data points.
