RK
- Comparison of Runge Kutta Schemes (Classical, Low-storage, low dissipation, 3rd-order, 4th-order etc.. )
Complexarithmetic
- 实现下列六种基本运算:1)由输入的实部和虚部生成一个复数;2)两个复数求和;3)两个复数求差;4)两个复数的求积;5)从已知复数中分离出实部;6)从已知复数中分离出虚部。运算结果以相应的复数或实数的表示形式显示。-To achieve the following six basic operations: 1) by the input of real and imaginary parts generate a plural 2) the sum of two complex numbers
OtsuThreshold
- otsu tresholding algorithm
sirt
- SIRT方法解线性方程组,通过迭代求解,取得了更为精确的结果,节省了计算时间-sirt mehtod to solve equation
doolittle
- LU分解在本质上是高斯消元法的一种表达形式。实质上是将A通过初等行变换变成一个上三角矩阵,其变换矩阵就是一个单位下三角矩阵。这正是所谓的杜尔里特算法(Doolittle algorithm):从下至上地对矩阵A做初等行变换,将对角线左下方的元素变成零,然后再证明这些行变换的效果等同于左乘一系列单位下三角矩阵,这一系列单位下三角矩阵的乘积的逆就是L矩阵,它也是一个单位下三角矩阵。 这类算法的复杂度一般在左右,对充分消元的分解则不然。 -LU decomposition is esse
build_matrix
