Interpolating Data with Interp1

Polynomial InterpolationAn important problem in various science and engineering applications is to find a polynomial whose graph passes through a specified set of points in the plane; this is called an interpolating polynomial for the points. Interpolating polynomials help scientists and engineers design solutions to problems or understand the mechanisms of the systems they study. A key skill for quantitative data analysis involves fitting models to data. A good model can be used to predict the
