Matlab polytool
The data at both ends of the plot tracks the fitted curve. The confidence bounds are closer together indicating that there is less uncertainty in prediction. This graph shows a much better fit to the data. Then, drag the vertical reference line to the x-value of 2 (or type 2 in the X Values text box). In the Degree box at the top, type 3 for a cubic model. The two points to the right are dragging down the estimate of the slope. You can analyze the impact of plant model uncertainty on control system performance, and. If a Matlab function is missing from the list and does not appear on the current release of the package, confirm. this entire section is about the current development version. Bugs are not listed here, search and report them on the bug tracker instead. Most things (arrays, matrices, plots, etc.) can be made into. Follows an incomplete list of stuff missing in the statistics package to be matlab compatible. But graphical interface is extremely convenient for standard tasks.

You can create uncertain models by combining nominal dynamics with uncertain elements, such as uncertain parameters or unmodeled dynamics. MatLab is essentially a programming language, and most things can be done from the command line, or by running program files. The bulk of the data with x-values between zero and two has a steeper slope than the fitted line. Robust Control Toolbox provides functions and blocks for analyzing and tuning control systems for performance and robustness in the presence of plant uncertainty. Dupaceasta data tema se penalizeaza cu 4 puncte. If you do not specify the degree of the polynomial, polytool does a linear fit to the data.

The variables x1 and y1 are data points from the "true" function without error. The variables x and y are observations made with error from a cubic polynomial. To start the demonstration, you must first load the data set.

You can use polytool to do curve fitting and prediction for any set of x-y data, but, for the sake of demonstration, the Statistics Toolbox provides a data set ( polydata.mat) to teach some basic concepts.
#Matlab polytool software
The polytool demo is an interactive graphic environment for polynomial curve fitting and prediction. Such as, polynomial of one indeterminate in Matlab software is adopted to return order: polytool (x, y, m) (p, Spolyfit (x, y, m), wherein, p is the rreturn value of polyfit function S is a matrix, is used for estimating predicated error X, y are data point, and m is polynomial expression exponent number) mathematical modeling recurrence.
