1 TUTORIAL 7 “Parabolic interpolation” I. OBJECT Understanding how to use and knowing the Parabolic interpolation to find an optimize point of equation in MATLAB Understand the structure and could develop the algorithm of the Parabolic interpolation II. PROCESS and RESULT 1. Introduction Parabolic interpolation is a technique for finding the minimum of a unimodal continuous function by successively fitting parabolas (polynomials of degree 2) to the function at three unique points. At each iteration one of the old points is replaced with the minimum of the fitted parabola. The point at which the fitted parabola is minimized is the approximation of the solution A parabola is the” simplest” function with an extreme value, the extreme value is attained at b/2a The location of the maximum/minimum of a parabola defined as the interpolation of three points (x1, x2, and x3) is: 2. Parabolic interpolation Algorithm The following algorithm can be used to determine the maximum of a function f(x).

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
