二次规划问题和MATLAB函数quadprog的使用小结

基于matlab的椭圆型低通滤波器设计程序(Based on matlab elliptic low-pass filter design)

Simple raytracer for MATLAB.

Manages very large tensors of arbitrary dimensions as mapped files on disk. (This class transparently maps large tensors of arbitrary dimensions to temporary files on disk. Referencing is identical to a standard matlab tensor, so a MappedTensor can be passed into functions without requiring that the function be written specifically to use MappedTensors. This is opposed to memmapfile objects, which cannot be used in such a way. MappedTensor also offers support for basic operations such as permute, without requiring space for the tensor to be allocated. An existing binary file can also be mapped, similarly to memmapfile. However, memmapfile offers more flexibility in terms of file format. )

PF,EPF,UPF的对比仿真代码，可以很直观的看出各种算法之间的差别及各自的优缺点。可直接运行。(PF, EPF, UPF contrast simulation code, it is intuitive to see the differences between the various algorithms and their respective advantages and disadvantages. Can be directly run.)

用双线性变换法设计IIR数字滤波器 （1）用双线性变换法设计一个巴特沃斯低通IIR 数字滤波器。设计指标参数为：在通 带内频率低于0.2π 时，最大衰减小于1dB；在阻带内[0.3π ,π ] 频率区间上，最小衰减大于15dB。 （2）以0.02π 为采样间隔，打印出数字滤波器在频率区间[0,π / 2] 上的幅频响应特性 曲线。 （3）用所设计的滤波器对实际心电图信号采样序列（在本实验后面给出）进行仿真滤 波处理，并分别打印出滤波前后的心电图信号波形图，观察总结滤波作用与效果。 (err)
