使用希尔排序法对一维数组排序

稀疏矩阵运算器进行矩阵的加减乘法，在进行乘法时用到行逻辑。-Sparse Matrix Arithmetic Unit for matrix multiplication, addition and subtraction, multiplication, when used during logic lines.

FFT（快速傅立叶变换）的算法实现-FFT (Fast Fourier Transform) algorithm

二分查找(Binary Search)　二分查找又称折半查找，它是一种效率较高的查找方法。　二分查找要求：线性表是有序表，即表中结点按关键字有序，并且要用向量作为表的存储结构。不妨设有序表是递增有序的。
