Note: this is similar to fitting data to a polynomial function using “polyfit” except the user must provide the function whose coefficients are to be determined. b0 represents the “initial guesses” for the parameters b1 and b2. In this case, they are both assumed to be 0.5.

[K can be obtained using the PolyFit function in Matlab. Plot the polynomial using the constants you obtained and compare it with the plot from your data. K will be the second order constant when the two plots fit closely. Use the K found to calculate Vt. Verify your Vt from the transistor data book.]

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 …

The following is an example MATLAB curve fit sequence using polyfit and polyval. Here is the plot reflecting our first try at fitting the data with a first degree polynomial (or a straight line). The coefficients given by MATLAB yield the following equation for the line: Trying a higher polynomial:

That means that the plot of versus should be close to a straight line. Using . polyfit, find an equation of a line that best fits the data given in the table. b) Using the results in part a) extract the value of . c) Using the numerical values provided, estimate the radius of the sphere 20.

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 =

You should start MATLAB by simply typing matlab if you are working on a Unix system or just by double clicking the MATLAB icon if you are using a Windows based system. If all goes well you will see a MATLAB prompt >> inviting you to initiate a calculation. In what follows, any line beginning with >> indicates typed input to MATLAB.

Using the polyfit function in Matlab®, draw a straight line through the data in your plot and find the y-intercept of the line. The y-intercept is the offset of the circuit. This offset is significant and arises as an artifact arising from non-ideal characteristics of the op-amps. In particular, there is a small offset in the voltage across ...

Rather than using polyfit I suggest using a pencil and paper since you will have to fit different parts of the record. A second velocity layer should be apparent if you recognize first-arrivals at larger shot-receivers distances x but that have a different slope than the line you fit above to the nearer receivers (see figure above).
