Function polyval - interpolation, MATLAB in Statistics

Assignment Help:

Function polyval - interpolation:

The function polyval can then be used to compute the polynomial at particular values. For illustration, we could compute at every value in the x vector:

>> curve = polyval(coefs,x)

curve =

63.8857   69.4571   71.3143   69.4571   63.8857

 

This results in y values for each point in the x vector, and stores them in a vector known as curve. Placing all this together, the script below known as polytemp generates the x &y vectors, that fits a second order polynomial through these points, and plots both points and curve on similar figure.
