说明：  matlab程序编写的一个8psk的调制程序，里面有一定的注释(matlab programming a 8psk modulation procedures, which have some comments)

低通IIR数字滤波器设计，用数字滤波器的单位脉冲响应序列h(n)模仿模拟滤波器的冲激响应ha(t),令 h(n)=ha(nT)，其中T为采样间隔。将模拟滤波器转换成数字滤波器的实质是，用一种从s平面到z平面的映射函数将Ha(s)转换成H(z)。数字滤波器的频率响应模仿模拟滤波器的频响，s平面的虚轴映射z平面的单位圆，相应的频率之间成线性关系。(Low-pass IIR digital filter design)

LDPC仿真程序,纠错码中的LDPC码，码长越长，纠错性能越好，是美国NASA深空通信运用的纠错编码(LDPC code for matlab)

This is a compilation of programming hints and examples about how to use and program MAT- LAB, with a mind on numerical methods. At present time, this is work in progress, so it s important to know which version of this document you are dealing with. There will not be detailed explanations of the examples: I will specically concentrate on where I think you might have trouble or you might be learning something new.

关于BPSK的误码率的MATLAB仿真程序。是在高斯信道（AWGN)下的仿真，能够生成图像形式。(BPSK bit error rate on the MATLAB simulation program. In the Gaussian channel (AWGN) under the simulation, can generate the image forms.)

matlab、C代码，实现图论中的大部分算法，包括kruskal、Dijkstra、prim、hamilton等 (Matlab,C code for most algorithms of graph theory.)

两个球面点源的干涉图样，主要用于分析在数字全息中球面波作为参考光的干涉图样。(interference of speherical wave)
