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

This gives you the best fit but you don’t know how wide the variances to the parameters of that fit are. In the next step, you take that best fit, add noise that conforms to your distribution of noise, and you re-fit this new set of data. ... Now I know that Matlab can make evenly (i.e. flat) distributed random numbers from 0→1 using the ...

MATLAB has two functions, polyfit and polyval, which can quickly and easily fit a polynimial to a set of data points. A first order polynomial is the linear equation that best fits the data. A polynomial can also be used to fit the data in a quadratic sense. As a reminder, the general formula for a polynomial is:
