An Simple Method for Sparse Matrix Optimization by GPU

这是一个相当simple & naive的方法，几行代码完成的CSR稀疏矩阵格式的优化，剔除0元素。由于目前AMD的OpenCL SDK依旧没有赶上NVIDIA CUDA SDK的进度——新的CUDA 4我认为在库的丰富程度上以及易用上已经远远的超过了AMD的实现。虽然如此，今后还是得希望开源社区能够贡献基于OpenCL的数学库，或者我自己搞一个？

This is a rare simple & naive method which is used to optimize sparse matrix, cull the all zero elements. I think the AMD’s OpenCL libraries is stil not as good as NVIDIA CUDA’s. Whatever, I wish there would be some mathmatics libraries from open source society, or I make one in person ?
