稀疏矩阵三元组顺序结构源码，可以作为头文件使用，方便那些初学数据结构的同学！-sparse matrix triple order of the source code structure can be used as the first document, facilitating data structure novice students!

A version with no branches in the loop. Eight insns in the loop, giving 8*32 + 2 = 258 insns worst case (however, the code above might be faster if the mask is sparse).-A version with no branches in the loop. Eight insns in the loop, giving 8*
