Polyfit and Polyval "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.

polyfit. and. polyval. Once you understood those functions, write a MATLAB script that allows you to fill in this table: Polynomial order: Predicted population in 2020; 2. 4. 6. 8. 10. Draw on the same plot the different fits obtained for polynomials of degree 2, 4, 6, 8, and 10. Comment your results.

In MATLAB you need to use p = polyfit(m, T, 11). The output from MATLAB is a vector with the coefficients of the polynomial from highest to lowest. 3. (3 points) Make a graph of the polynomial. In MATLAB you can use the following to make the graph. m1 = linspace(0, 11, 111); Tpoly = polyval(p, m1); plot(m, T, '*', m1, Tpoly, ':'). Based on this ...

Using MATLAB, fit the same data to this new model, using the initial estimates C=10, a=2 . Because this equation is not a polynomial function, you cannot use polyfit, and will instead use a more generic minimization function called fminsearch (see hints at end). Plot the …

ap=polyfit(t,Y,1) ap =-0.5017 2.1098. You should notice that the first element in vector ap is the coefficient of the highest degree term. This is the convention used by Matlab in any polynomial functions. The experimental data and the best fitted line can be plotted by the following Matlab statements >> ycal=polyval(ap,t) ycal =
