these are a matlab sources codes, which give a solution for the game of life, with some diferents modes of operation. enjoy the code :)

针对初学者的Matlab界面编写。适合初级入门者学习。(Matlab interface to write for beginners. Suitable for junior beginners to learn.)

说明：  1、主要是产生0，1，2，3，阶贝赛尔函数图形。 2、产生线性调频信号和它的的频谱图。 3、产生单个脉冲的三维模糊图以及对应的等值图。 4、它是程序3的嵌套子程序，用于产生单个脉冲。 5、用于产生高斯和瑞利分布函数。 (These programs can produce 1、Bessel graph；2、LFM signal and its amplitude spectrum；3、ambiguous graph 4、Gaussian and Rayleigh function. )

利用Matlab软件编程实现DDS（直接数字频率合成技术）。设时钟的频率为固定值f_C，在CLK的作用下，如果按照0000,0001,0010，…，1111的地址顺序读出ROM中的数据，即表1中的幅值编码，其正弦信号频率为f_01；如果每隔一个地址读一次数据（即按0000,0001,0100，…，1110顺序），其输出信号频率为f_02，且f_02将比f_01提高一倍，即f_02=2f_01；其余类推。这样，就可以实现直接数字频率合成器的输出频率的调节。(Matlab software programming DDS (direct digital frequency synthesis). Clock frequency set to a fixed value f_C, under the effect of CLK, according to 0000,, ..., 1111 of the sequence of addresses in the ROM reads the data, i.e., the amplitude of the encoding in Table 1, the frequency of the sinusoidal signal f_01 if every time a read address data (ie 0000,0001,0100, ..., the order of 1110), the output signal frequency is f_02, and f_02 f_01 than doubled, i.e. f_02 = 2f_01 rest on. This allows direct digital frequency synthesizer output frequency regulation.)
