libsvm matlab 上的安装

简介windows上matlab安装还是有一些坑的

首先 matlab2016a 安装一个 编译器 tdm64-gcc-4.9.2.exe
然后更改 libsvm 中的matlab make.m 重点观察 $CFLAGS

% This make.m is for MATLAB and OCTAVE under Windows, Mac, and Unix
function make()
try
	% This part is for OCTAVE
	if (exist ('OCTAVE_VERSION', 'builtin'))
		mex libsvmread.c
		mex libsvmwrite.c
		mex -I.. svmtrain.c ../svm.cpp svm_model_matlab.c
		mex -I.. svmpredict.c ../svm.cpp svm_model_matlab.c
	% This part is for MATLAB
	% Add -largeArrayDims on 64-bit machines of MATLAB
	else
		mex CFLAGS="$CFLAGS -std=c99" -largeArrayDims libsvmread.c
		mex CFLAGS="$CFLAGS -std=c99" -largeArrayDims libsvmwrite.c
		mex CFLAGS="$CFLAGS -std=c99" -I.. -largeArrayDims svmtrain.c ../svm.cpp svm_model_matlab.c
		mex CFLAGS="$CFLAGS -std=c99" -I.. -largeArrayDims svmpredict.c ../svm.cpp svm_model_matlab.c
	end
catch err
	fprintf('Error: %s failed (line %d)
', err.stack(1).file, err.stack(1).line);
	disp(err.message);
	fprintf('=> Please check README for detailed instructions.
');
end
