check2dgauss.m

具有图形操作界面的支持向量机多类分类实验系统.全部用Matlab实现,可以实现多种分类识别. 这是本人的毕业设计的附属程序

function res = check2dgauss(fname)
% CHECK2DGAUSS Checks if given file containes bivariate Gaussians.
%
% Synopsis:
%  res = check2dgauss(fname)
%
% Description:
%  If the file 'fname' contains a matrix Mean [2 x ncomp],
%  a matrix Cov [2 x 2 x ncomp] and a vector y [1 x ncomp]
%  then it returns 1 else it returns  0.
%
% Input:
%  fname [string] File name.
% 
% Output:
%  res [1x1] Equals to 1 if it is valid file otherwise 0.
