IIR
用双线性变换法设计IIR数字滤波器
滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)

MATSLISE2006
MATSLISE is a Matlab application for the numerical study of Schringer
and Sturm-Liouville problems. MATSLISE allows one to compute the eigen-
values and eigenfunctions and to display them graphically.
The numerical methods used are the CP methods (abbreviation for
Constant reference potential Pertubation Method).

r_huffman
一般教材上讲诉的是如何用MATLAB实现一元或二元的霍夫曼编码，而这个是实现r（r>2）元的霍夫曼编码。(Generally speaking textbook complaint is how to use MATLAB to achieve mono- or dicarboxylic Huffman encoding, and this is the realization of r (r> 2) yuan Huffman coding.)
