三次样条插值法，（Matlab实现）以其中第一类边界条件来实现。(Clamped Cubic Spline interpolation based on Matlab.)

[X,Y,Z]=cylinder2(x,y,z,r,N,o) 向量X，Y，Z轴定义圆柱面中心线 和矢量r定义圆柱面半径，并已 为的x，y，z的长度相同 N是周围围点的数量。默认值 为N= 100。 Ø 定义了矩阵圆柱generatix（圆圈）椭圆 表面。其内容以0和1之间的值，并适用于 小学和中学的母线轴。值的defeault Ø =的（长（x），2）。 矩阵X，Y，Z轴确定圆柱面，冲浪（的X，Y，Z）的显示器 圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o) Vectors x, y, z define the central line of cylindrical surface and vector r defines the radius of cylindrical surface, and has the same length as x, y, z. N is the number of points around the circumference. The default value is N = 100. Matrix o defines ovality of the generatix (circle) of cylindrical surface. Its elements take values between 0 and 1 and apply to the primary and secondary axis of generatrix. The defeault values are o=ones(length(x),2). Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays the cylindrical surface. )

shearlet工具箱。里面有基于剪切波的图像去噪算法，实验结果表叫，它较原有算法更好地实现去除噪声与保护图像细节之间的平衡(Threshold-based shearlet image denoising algorithm, called the results table, it better than the original algorithm to remove noise and to achieve a balance between preserving image details.)
