Scientific Computing. Numerical Solution Of Ordinary Differential Equations - Runge-Kutta Methods. Runge-Kutta Methods. If we take more terms in the Taylor’s Series expansion of f(t,x), we would get a more accurate solution algorithm.

Scientific Computing. Linear Systems – Gaussian Elimination. Linear Systems. Linear Systems. Solve Ax=b, where A is an n n matrix and b is an n 1 column vector We can also talk about non-square systems where A is m n , b is m 1, and x is n 1

Scientific Computing. Introduction to Matlab Programming. Today. We will introduce the programming environment for our course: Matlab We will cover: Basic Operations, Functions, Plotting Vectors, Looping Creating a new Function in a M-file. Why Matlab?.

Scientific Computing. Dr. Guy Tel- Zur. Version 28-05-2011.12:40. Agenda. Administration Visualization Visualization in Sage VisIt : Tutorial The Silo file format A demo program Animation Demo : AWS – HTC Instance for Parallel Computing and Cellular Automata / NKS demo on the cloud

Scientific Computing. Partial Differential Equations Explicit Solution of Heat Equation. The one-dimensional Heat Equation for the temperature u(x,t) in a rod at time t is given by: where c >0, T>0 are constants. One Dimensional Heat Equation.

Scientific Computing. Interpolation – Divided Differences Efficiency and Error Analysis. How is Interpolation used?. Here is a table of values for the temperature at a given depth for a lake. We want a good estimate of the temperature at a depth of 7.5 meters. Newton’s Nested Formula.

Scientific Computing. Linear Systems – LU Factorization. LU Factorization. Today we will show that the Gaussian Elimination method can be used to factor (or decompose ) a square, invertible, matrix A into two parts, A = LU, where:

Scientific Computing. Numerical Solution Of Ordinary Differential Equations - Euler’s Method. Bungee Jumper – Coupled ODEs. Bungee Jumper – Coupled ODEs. We want to model the vertical dynamics of a jumper connected to a stationary platform with a bungee cord. F=ma Forces :
