**gray_scott_movie**,
a MATLAB code which
solves versions of the partial differential equation (PDE) known
as the Gray-Scott reaction diffusion equation, converting the
solutions to a sequence of graphics frames, which are then
assembled into a movie.

**gray_scott_movie** is available in
a MATLAB version.

cavity_flow_movie, a MATLAB code which animates the velocity solutions for the driven cavity;

cvt_1_movie, a MATLAB code which creates an animation of the evolution of a Centroidal Voronoi Tessellation (CVT) in the unit square.

cvt_2_movie, a MATLAB code which animates the generation of a Centroidal Voronoi Tessellation (CVT) in the unit square, which includes a random "rebirth" at every iteration.

cvt_3_movie, a MATLAB code which animates the generation of a Centroidal Voronoi Tessellation (CVT) for the "holey pie" region.

cvt_4_movie, a MATLAB code which creates a Centroidal Voronoi Tessellation (CVT) movie in a square, with a density function that drives points to the corners;

cvt_corn_movie, a MATLAB code which makes a movie in which the growth of a corn kernel is simulated using a Centroidal Voronoi Tessellation (CVT).

gray_scott_pde, a MATLAB code which solves the partial differential equation (PDE) known as the Gray-Scott reaction diffusion equation, displaying a sequence of solutions as time progresses.

peak_movie, a MATLAB code which creates a sequence of frames, and then an animation or movie from the data displayed by the peaks() function.

pendulum_double_ode_movie, a MATLAB code which solves the double pendulum ordinary differential equation (ODE) for a given set of initial conditions and parameters, and makes a movie of the results.

shallow_water_1d_movie, a MATLAB code which solves the partial differential equation (PDE) known as the shallow water equations (SWE), converting the solutions to a sequence of graphics frames, which are then assembled into a movie.

spiral_pde_movie, a MATLAB code which solves a pair of reaction-diffusion partial differential equations (PDE) over a rectangular domain with periodic boundary condition, whose solution is known to evolve into a pair of spirals. The sequence of solutions is bundled into a movie.

tetrahedron_slice_movie, a MATLAB code which is given a tetrahedron and a vector, displays an evenly spaced sequence of planes that intersect the tetrahedron and are normal to the vector, and creates a movie of the process.

- gray_scott_movie.m solves a specific Gray-Scott reaction diffusion equation, converts the solutions to graphics frames, and assembles them into a movie.
- i4_wrap.m forces an integer to lie between given limits by wrapping.
- laplacian9_torus.m uses a 9 point Laplacian stencil on a rectangular grid.
