根据读取到的已知控制点的坐标，计算在该区域内的平面转换五参数，该五参数不同于当前使用较多的四参数(According to the known control point to read the coordinates to calculate the plane in the region converted five parameters, the five parameters to use more different from the current four-parameter)

一副图可视为一个矩阵，将其分成上线两部分，然后用矩阵的合并实现两个图简单拼接。目的主要使新手熟悉matlab的这种图形处理方法。(A diagram can be regarded as a matrix, to be divided into on-line in two parts, and then use the matrix of the merger of two diagrams simple splicing. The main purpose of the novice familiar with Matlab this graphical approach.)

数值求Mittag-Leffler function，这个给出一个多参数的求值，可用在数值仿真。(Solve the value of Mittag-Leffler function, which can be applied the simulink in Matlab.)

ITU标准下的大气传播衰减计算程序，使用简单方便，只需要输入传播角度，高度，气候环境，即可计算大气传输损耗（不包括自由空间传播损耗）(According to the ITU standard, this program calculates the atmospheric loss. It is simple to use, you only have to input some parameters such as height, elevation angle, etc)

模糊控制,属于控制器的设计范畴，此处给出的是仿真图(Fuzzy control, which belongs to the design category of the controller, is given here is the simulation diagram)

说明：  针对低信噪比环境下基于能零比的端点检测方法准确率低的问题,提出了一种结合谱减法和短时零熵法的端点检测方法。首先通过功率谱减法对带噪语音进行降噪处理,然后结合短时平均过零率特征与谱熵特征,构造出一种新的语音参数,即短时零熵,最后运用双门限算法进行端点检测。实验结果表明该方法在复杂噪声环境下具有良好的端点检测性能,降低了检测的误判率。(To solve the problem of low accuracy of endpoint detection method based on energy zero ratio in low SNR environment, an endpoint detection method combining spectral subtraction and Short-term zero entropy method is proposed. Firstly, the noise is reduced by power spectrum subtraction, then a new speech parameter, short-time zero entropy, is constructed by combining the short-time average zero crossing rate and spectral entropy. Finally, the double threshold algorithm is used for endpoint detection. The experimental results show that this method has good performance of endpoint detection in complex noise environment, and reduces the rate of detection error.)
