PNG開放源接口 The interface has
been designed to be as simple and intuitive as possible. It supports plotting and reading in the RGB (red, green,
blue), HSV (hue, saturation, value/brightness) and CMYK (cyan, magenta, yellow, black) colour spaces, basic
shapes, scaling, bilinear interpolation, full TrueType antialiased and rotated text support, bezier curves, opening
existing PNG images and more.
Programs in the irregular grid design package described in this manual are used to carry out five main functions:
verification and adjustment of coastline and bathymetric data
preparation of an irregular triangular depth grid covering the domain to be modelled
production of a preliminary irregular triangular model grid with nodes suitably positioned for accurate and efficient numerical modelling
interactive checking and editing, including trimming and joining, of model grid
display and plotting of model output.
% EM algorithm for k multidimensional Gaussian mixture estimation
%
% Inputs:
% X(n,d) - input data, n=number of observations, d=dimension of variable
% k - maximum number of Gaussian components allowed
% ltol - percentage of the log likelihood difference between 2 iterations ([] for none)
% maxiter - maximum number of iteration allowed ([] for none)
% pflag - 1 for plotting GM for 1D or 2D cases only, 0 otherwise ([] for none)
% Init - structure of initial W, M, V: Init.W, Init.M, Init.V ([] for none)
%
% Ouputs:
% W(1,k) - estimated weights of GM
% M(d,k) - estimated mean vectors of GM
% V(d,d,k) - estimated covariance matrices of GM
% L - log likelihood of estimates

The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding
by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been
implemented for a 2x2 system. The reader can program other variations.
The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.
