Polynomial Interpolation) (a) Write a MATLAB function M-file called pv polyinter p (x, y) that will input two vectors x and y of the same length (call this length " n +1 " for now) that correspond to the JC- and ^-coordinates of n +1 data points on which we wish to interpolate with a polynomial of degree at most n.
Plot the function values and the polynomial fit in the wider interval [0,2], with the points used to obtain the polynomial fit highlighted as circles. The polynomial fit is good in the original [0,1] interval, but quickly diverges from the fitted function outside of that interval.
p = polyfit(x,y,n) returns the coefficients for a polynomial p(x) of degree n that is a best fit (in a least-squares sense) for the data in y. How do you plot a polynomial fit on a graph? Plot the function values and the polynomial fit in the wider interval [0,2], with the points used to obtain the polynomial fit highlighted as circles.
This MATLAB function returns the coefficients for a polynomial p(x) of ... Plot the function values and the polynomial fit in the wider interval [0,2] ...
Please help me plotting this polynomial. how much should the range be , it seems matlab is not able to solve it. here is the function: = (1 / x ) [2.125 x^4 ...
The polynomial coefficients in p can be calculated for different purposes by functions like polyint, polyder, and polyfit, but you can specify any vector for the coefficients.. To evaluate a polynomial in a matrix sense, use polyvalm instead.
