一个用fortran90编写有限元流体求解器，包括使用源代码，输出文件和单元文件，推荐学习使用-Prepared using a finite element fluid fortran90 solver, including the use of source code, the output file and the unit document and recommend learning to use

误差分析的方法有多种，这是一种先验估计误差的方法，较以往的“向前误差分析”在矩阵运算的舍入误差估计上有较好的结果，以而使矩阵的误差分析获得了突破性的进展，使不少用向前误差分析难于判定可靠性的数值方法获得新的进展。特别值得一提的是，在工程技术界，经常使用几种不同的计算方法，甚至使用实验方法进行比较，从而确定计算结果的可靠性，这也是一种有效而实用的方法。-error analysis by a number of means, which is a priori estimation error method, compared to the previous "Forward Error Analysis" in the matrix calculation error into the homes a better estimate on the results of a matrix so the error analysis of a breakthrough in the progress, many with forward error analysis can be difficult to determine on the numerical method to achieve new progress. Particularly worth mentioning is that in the engineering technology sector, often use several different methods of calculation, or even the use of experimental methods, in order to determine the reliability of results, which is also an effective and practical method.

C[i,j] 表示点i+1，i+2到点j中，选择任意一个点作为根，在（j-i）个解中找出成本最小的最优解 向前递推过程： 首先计算所有j-i=1的C(i, j) 然后依次计算j-i=2,3,…,n的C(i,j)。 C(0,n)=最优二分检索树的成本。 初始值 C(i,i) = 0 W(i,i) = Q(i)，0≤i≤n 最优二分检索树的构造 在计算C(i, j)的过程中，记下使之取得最小值的k值，即树Tij的根，记为R(i, j)。 依据R(0, n)…，推导树的形态
