This GUI draws a seashell, using a parametric surface. The parameters of the seashell can be modified with sliders and buttons in the GUI. See also the "seashell.m" file, also on MATLAB Central (with no GUI).

find_components finds the connected components of an image. Two pixels are in the same component if they are adjacent (north, south, east, or west, but not NW, SW, etc) and have the same value. This was a bit of recreational weekend programming, in reply to Doug Hull's Puzzler of Aug. 18, 2008: http://blogs.mathworks.com/pick/2008/08/18...nnected-island/ It also serves as a nice example of DMPERM. To read more about dmperm, and to read its code, see CSparse or CXSparse on the File Exchange.

The "GEE! It's Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=Ab, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package. For a detailed derivation of Gaussian elimination with partial pivoting, see Sections 3.1 and 6.3 of "Direct Methods for Sparse Linear Systems", Davis, SIAM, 2006 ( http://www.ec-securehost.com/SIAM/FA02.html ), or "Numerical Computing with MATLAB" by Cleve Moler, SIAM, 2004.

MESHND is an M-file toolbox for creating 2D and 3D meshes and ordering them with nested dissection. It can also create a sparse matrix from a regular mesh using an abitrary stencil. Examples: A = meshsparse (meshnd (7,5,2)) creates a 7-by-5-by-2 mesh, and then computes the sparse matrix A that represents the mesh (using a 7-point stencil). You can specify other stencils (5, 7, 9, and 27-point) or create your own to pass to meshsparse. This example creates the same mesh but also finds the nested dissected ordering of that mesh: [G p] = meshnd (7,5,2) ; A = meshsparse (G) ; subplot (1,2,1) ; spy (A) ; subplot (1,2,2) ; spy (A (p,p)) ; Here is a simple view of small mesh. [G p pinv Gnew] = meshnd (4,5) returns <pre> Gnew = 1 2 17 9 10 7 8 18 15 16 3 5 19 11 13 4 6 20 12 14 G = 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17...
