简单的视频水印嵌入算法 matlab开发 不错的源码 很好(Simple video watermarking embedding algorithm matlab development good source is very good)

这是一个图形学应用的小程序，可以实现简单的填充功能。(This is a small graphics application procedures, can be filled with simple functions.)

这是NURBS曲线的绘制程序，在MATLAB-2008a环境下进行编写，包含了几个基函数子程序。可以通过调节控制顶点和点的权重来调节曲面形状。 (This is a NURBS curve drawing program, in the MATLAB-2008a environments prepared, including a number of basis function subprogram. Can be controlled by adjusting the weight of vertex and point to adjust the surface shape.)

AUTO CAD 2013破解程序，非常好用，使用多次均能成功。(AUTO CAD 2013 crack program)

系统辨识作业 考虑如下模型 z(k)-1.5z(k-1)+0.7z(k-2)=u(k-1)+0.5u(k-2)+v(k) 其中v(k)是均值为0，方差为1的白噪声。根据模型生成数据，采用递推最小二乘法对模型参数进行辨识，要求绘出各参数随时间的变化曲线。 ("System identification" computer test 。Consider the following model Z (k) to 1.5 of z (k- 1)+ 0.7 z (k- 2) = u (k- 1)+ 0.5 u (k- 2)+ v (k) The v (k) is the mean to 0, the white noise variance 1. Generate data according to the model, the recursive least squares method is adopted to model parameters are identified, draw the parameters changing with time curve. )
