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 ...

polyfit finds the coefficients of a polynomial that fits a set of data in a least-squares sense. p = polyfit(x,y,n) x and y are vectors containing the x and y data to be fitted, and n is the order of the polynomial to return. ... In Matlab the function name must be the same as the filename ! end is sometimes unnecessary. function using @

[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.]

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 =

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 best model prediction and the data on the same plot.

"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.
