Find the best fit quadratic curve through the set of points whose coordinates are stored as X2 and Y2 in the workspace quadratic.mat. See what happens if you try to find the best fit quadratic curve in problem 8 without first eliminating the outlying points.

Earlier during the course, we examined a Markov process that modeled the brand loyalty of Windows, Mac and Linux users. We came up with the following model: x n y n z n = 0.6 0.05 0.2 0.1 0.94 0.05 0.3 0.01 0.75 A n x 0 y 0 z 0 We found the steady state distribution of the system by observing that the transition matrix had a limit as n goes to infinity, and we approximated that limit A ∞ by ...

MATLAB PLOT: Plot . time . on the x-axis and . height. on the y-axis. Add axis labels (with units) and a title to your plot. We know the height of the projectile follows a parabolic (2nd order) curve. So use the curve fitting tool to fit a 2nd order polynomial (quadratic) to the height data.

Figure 26 shows the plot obtained from Matlab. Fig 26: Quadratic Curve Fit for Cost Rate Curve. Clearly, the curve is inaccurate for very low values of power (note it is above $605/hr at P=0 and decreases to about $590/hr at P=10). We can get the incremental cost curve by differentiating C(P): IC(P)=0.1806P-2.9553

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. 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 ...

Because we are finding the area under the curve from we must use three points, and to fit a quadratic polynomial through the data. Using polynomial interpolation, our resulting velocity function is (refer to notes on direct method of interpolation) Now, we simply take the integral of the quadratic …

(The best fit for Hassell's model was found using the fminsearch routine in MatLab, while the Logistic growth model used Trendline in Excel.) With the 3 parameters to fit the curve to the data, Hassell's updating function is capable of fitting the data better than the quadratic …
