MATLAB POLYTOOL EXPORT CODE

To change from least squares to a robust fitting method, use the Method menu. To change the type of confidence intervals, use the Bounds menu. To change the degree of the polynomial, choose from the pop-up menu at the top of the figure. The argument n controls the degree of the polynomial fit.

The Polytool is crafted by placing a 4 full stacks of Carbon Nanotubes into the Chemical Synthesis Machine configured so that the top-center, left-center, right-center, and bottom-center slots each have a full stack. The shape of the pointer changes from an arrow to a cross hair when you are over the vertical line to indicate that the line can be dragged. The Polytool is an all-in-one tool that combines an axe, pickaxe, shovel and sword and that can be upgraded with elements to add effects or to alter the tool speeds. Polytool fits by least-squares using the regression modelД®valuate the function by typing a value in the x-axis edit box or by dragging the vertical reference line on the plot. m file and open it in a text editor, you will see the commands you can use in MATLAB. There you will be able to select the different native and user-derived variable (if any) as export data. Plots 100(1-alpha) % confidence intervals on the predicted values. Right click on the results node and add an Export. Text with current predicted value of y and its uncertainty appears to the left of the y-axis. The plot shows the fitted curve and 95% global confidence intervals on a new predicted value for the curve. This plot is graphic user interface for exploring the effects of changing the polynomial degree of the fit. Interactive plot for prediction of fitted polynomialsДЇits a line to the column vectors x and y and displays an interactive plot of the result. If d >= 2 % For terms of degree > 1, add power of x.Д = d - 1 % Increment loop: Add term of next lowest degree.Polytool (Statistics Toolbox) Statistics Toolbox If d > 0 % For nonconstant polynomials, add *. If a ~= 1 || d = 0 % Add coefficient if it is ~=1 or polynomial is constant. % POLYSTR Converts a vector of polynomial coefficients to a character string.Д = length(p) - 1 % Degree of polynomial. Type polystr.m % Display contents of polystr.m file The polystr.m file defines the polystr helper function. Legend('Data','Fit','Roots of Fit','95% Prediction Intervals')ДЄlternatively, you can use polytool for interactive polynomial fitting. Plot(ењЋxtended,zeros(size(ењЋxtended)),'k-') Plot(ењЋxtended,yfitExtended+deltaExtended,'r-') Plot(ењЋxtended,yfitExtended-deltaExtended,'r-') XExtended = linspace(xmin - 0.1*xrange, xmin + 1.1*xrange,1000) Then, plot the roots and the estimations. Estimate the fitted values and prediction intervals for the x interval that includes the roots. Title()Д«ecause the roots are real values, you can plot them as well.

Plot the data and the estimations, and display the fitted polynomial expression using the helper function polystr, whose code appears at the end of this example.

Fit a polynomial to a sample data set, and estimate the 95% prediction intervals and the roots of the fitted polynomial.
