Close3B
- 采用拟三对角矩阵反算出过一定点（大于等于3个）的控制顶点，再由这些控制顶点计算出3次B样条曲线，由于曲线封闭的，所以无需引入边界条件即可求得曲线。-Used to be anti-tridiagonal matrix calculated over a certain point (greater than or equal to 3) of the control points and then calculate the control points of these 3 B-spline
wavelet
- 根据对所输入的png格式的真彩图像、小波类型（db9或haar）和相应的阈值进行了三级非标准小波harr或db9分解处理，并把经过三级非标准小波分解后的各颜色分量的各级水平细节分量、垂直细节分量、对角细节分量矩阵完成了相应矩阵元素数值小于阀值系数的个数统计和对矩阵元素数值小于阀值系数进行置0处理。最后进行了三级非标准小波重构，从而达到了对原图像的压缩处理的目的。-wavelet trasform of image
matrix
- 计算五对角矩阵的简单算法，为计算数值方法提供了一定的基础。-calculate matrix
