pdfplot
显示一个经验概率密度函数在输入数组中的密度分布直方图X的使用nbins箱的数目（默认pdfplot套nbins至20）。如果输入X是一个矩阵，然后pdfplot（X）的分析它的载体，并显示所有值的PDF格式。对于复杂的输入X，pdfplot（X）的显示PDF格式的(displays a histogram of the empirical probability density function (PDF)
for the data in the input array X using nbins number of bins
(by default pdfplot sets nbins to 20).
If input X is a matrix, then pdfplot(X) parses it to the vector and
displays PDF of all values.
For complex input X, pdfplot(X) displays PDF of abs(X).

Field_Examples
Field Ⅱ超声成像代码，可以进行单个孔径成像和合成孔径成像、加权和不加权仿真。(The calculation of point spread functions is done by placing a point in front of the transducer and then sweeping the beam over the point. This gives the point spread function of the imaging system. Field II can make this calculation for a number of points simultaneously and thereby reveal the dynamic focusing properties of the imaging system. A point phantom has been made for this purpose. It consists of a number of point targets placed with a distance of 5 mm starting at 15 mm from the transducer surface)

baseband_detection_simulink
In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered
at the detector output.

AWGN
AWGN信道的设计与仿真加性高斯白噪声在通信领域中指的是一种各频谱分量服从均匀分布（即白噪声），且幅度服从高斯分布的噪声信号。因其可加性、幅度服从高斯分布且为白噪声的一种而得名。(Design and Simulation of additive white Gaussian noise AWGN channel in the middle of the field of communication is a uniform distribution of each spectral component (ie, white noise), and the amplitude of the noise signal to obey a Gaussian distribution. Because it can increase resistance, the magnitude of Gaussian distribution and is named after a white noise.)

遗传算法程序
说明： 遗传算法是计算数学中用于解决最佳化的搜索算法，是进化算法的一种。进化算法最初是借鉴了进化生物学中的一些现象而发展起来的，这些现象包括遗传、突变、自然选择以及杂交等。遗传算法通常实现方式为一种计算机模拟。对于一个最优化问题，一定数量的候选解（称为个体）的抽象表示（称为染色体）的种群向更好的解进化。传统上，解用二进制表示（即0和1的串），但也可以用其他表示方法。进化从完全随机个体的种群开始，之后一代一代发生。在每一代中，整个种群的适应度被评价，从当前种群中随机地选择多个个体（基于它们的适应度），通过自然选择和突变产生新的生命种群，该种群在算法的下一次迭代中成为当前种群。(Genetic algorithm (GA) is a search algorithm used to solve optimization in computational mathematics. It is one of evolutionary algorithms.
Evolutionary algorithms were originally developed by borrowing phenomena in evolutionary biology, such as heredity, mutation, natural selection and hybridization.
Genetic algorithms are usually implemented as a computer simulation.
For an optimization problem, an abstract representation of a certain number of candidate solutions (called individuals) (called chromosomes) evolves towards a better solution.
Traditionally, solutions are represented in binary (that is, strings of zeros and ones), but other representations are possible.
Evolution begins with a population of completely random individuals, and it happens from generation to generation.)
