Interpolation. ? When you take data, how do you predict what other data points might be? ? Two techniques are : • Linear Interpolation. – Assume data follows a straight line between adjacent measurements. • Cubic Spline Interpolation. – Fit a piecewise 3rd degree polynomial to the data points to give a. “smooth" curve to

Interpolation is used to estimate data points between two known points. The most common interpolation technique is Linear Interpolation. • In MATLAB we can use the interp1() function. • The default is linear interpolation, but there are other types available, such as: – linear. – nearest. – spline. – cubic. – etc. • Type “help
which simply connects each data point with a straight line. • The polynomial that links the data points together is of first degree, e.g., a straight line. 0. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 0. 2. 4. 6. 8. 10. 12.

9. Choosing Interpolant. Choice of function for interpolation based on. ? How easy function is to work with. ? determining its parameters. ? evaluating function. ? differentiating or integrating function. ? How well properties of function match properties of data to be fit (smoothness, monotonicity, convexity, periodicity, etc.)
Two types of curve fitting. • Least square regression. Given data for discrete values, derive a single curve that represents the general trend of the data. — When the given data exhibit a significant degree of error or noise. • Interpolation. Given data for discrete values, fit a curve or a series of curves that pass di- rectly through
