viterbi译码算法的matlab源代码(viterbi decoding algorithm matlab source code)

说明：  BP神经网格预测，可用与各种波形的预测 比如经济的、机械振动信号等(ANN—BP wave forcast)

The proposed approach satisfies the integrability condition and does not need any boundary condition assumptio-ns, we have designed a stand-alone, flexible Matlab implementation that enables to evaluation the proposed approach. The experiments on real images show the approaches ability to reconstruction the surface from SFS.

vc和mat混合编程，利用matlab的com组件来实现mat和vc的混合编程(vc and mat mixed programming, the use of matlab' s com vc components to achieve mat and Hybrid Programming)
