Extremely Fun Physics Based Game Tiny Ball vs. Evil Devil was the number 2 free app overall in the US and top 10 free app overall in 31 countries. Download it today! (09-07-11) The Tiny Ball needs your help in getting his ship back from the Evil Devil! Play this fun, addicting, and challenging...

The entire game uses the ODE (Open Dynamics Engine) library for realistic game physics.

The script quasi_newton_dfp.m optimizes a general multi variable real valued function using DFP quasi Newton method. During the iterations if optimum step length is not possible then it takes a fixed step length as 1. For the theory any good book on optimization techniques can be consulted. This...

Two methods are provided -1) an automatic updation method which can be effectively used outside of a loop since it writes out a newton-raphson computation file from the parameters received.2) a manual file generation method; effective when the resulting file has to be called repeatedly in a loop.


Platforms: Matlab

Matlab files include Gaussian numerical quadrature, Newton's method for finding roots, finite element method for 1D wave equation, and pattern formation (KPP anda system of two coupled PDEs).

All you have to do is to place the accelerometer in 9 different static positions and record the x, y & z values.The procedure exploits the fact that, in static conditions, the modulus of the accelerometer output vector matches that of the gravity acceleration. The calibration model incorporates...

In this there are three files.In fun.m file input the function. In dfun.m file input the derivative of the function and then just run the Newton.m file. It will input the Tolerence, No of Iterations and the Initial Value. Finally it will display the No of iterations and the root.


Platforms: Matlab

Use newton_pendulum and the simulation and animation will start.

The Ejs First Law model displays the dynamics of a ball subject to no net force. The initial conditions for the ball are an initial velocity in the x and y directions. The initial position of the ball can be changed by dragging it when the simulation is paused. You can modify this simulation if...

The Ejs Hard Disk Gas model displays a two-dimensional gas made out of hard disks. Particles are initialized with a speed v=1 in a random direction and move with constant velocity until a collision occurs. You can modify this simulation if you have Ejs installed by right-clicking within the plot...
