The following is the built-in humps function that MATLAB uses to demonstrate some of its numerical capabilities:

The humps function exhibits both flat and steep regions over a relatively short x range. Here are some values that have been generated at intervals of 0.1 over the range from x = 0 to 1:

X

0.1

0.2

0.3

0.4

0.5

f(x)

5.176

15.471

45.887

96.500

47.448

f(x)

11.692

12.382

17.846

21.703

16.000

 

Fit this data with a (a) cubic spline with not-a-knot end con­ditions and (b) piecewise cubic Hermite interpolation. In both cases, create a plot comparing the fit with the exact

humps
function.
