与矩阵连乘最小乘法数问题类似，虽然不需要记录加括号的方式，但是需要纪录下从i乘到j的结果中为a、b、c的个数，以便在后续的计算中可以用到之前的数据，避免重复计算。所以就需要用三维数组来存储（当然用struct结构体数据类型也很方便）或者用两个数组。
With a matrix with minimal multiplication problem similar, although need not record bracketed style, but need to record from I to take the j results for a, B, C numbers, in order to follow-up calculation can be used before the data, avoid to repeat computation. So we need to use three-dimensional array to store ( of course with the structure of the struct data type is also very convenient ) or a two array. (2012-05-21, Visual C++, 289KB, 下载2次)

其基本思想是取B样条函数 为及基函数，在[a,b]中均匀划分区间，xi=a+ih,h=(b-a)/n,由于三次样条函数空间是n+3维的，所以把分点扩充到x-1,xn+1,则任意三次样条函数可用 线性组合来表示：
The basic idea is to take B-spline function and basis functions in [a, b] in the evenly divided intervals, xi = a+ ih, h = (ba)/n, because the cubic spline function is n+3 dimensional space , so the expansion points to the x-1, xn+1, then any cubic spline function can be expressed as a linear combination: (2011-10-14, Visual C++, 6KB, 下载6次)
