check2ddata.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=check2ddata(fname)
% CHECK2DDATA Checks if given file containins labeled 2D vectors.
% 
% Synopsis:
%  res = check2ddata(fname)
%
% Description:
%  If the file 'fname' contains matrix X [2 x num_data]
%  and a vector y [1 x num_data] then it returns 1
%  else it returns 0.
%
% Input:
%  fname [string] File name.
% 
% Output:
%  res [1x1] Equals to 1 if it is valid file of 2D data otherwise 0.
