希尔伯特黄变换程序，里面还有emd变换的程序，希尔伯特黄变换的画图工具，能画出模态函数瞬时频率图像(Hilbert-Huang transform procedures, there EMD transform procedure, and the instantaneous frequency of the Hilbert-Huang transform image)

说明：  Matlab基础及其应用教程，pdf文档(Matlab basis of its application tutorials, pdf document)

在目标识别中利用结构化支持向量机加快评估过程而不降低精度(Using ranking SVM to accelerate the uation process of Object Recognition without decreasing accuracy)

在人们的生产活动和社会活动中常常会遇到这样的问题：经过一段时间之后，需要对具有相同类型的部门或单位（称为决策单元）进行评价，其评价的依据是决策单元的“输入”数据和“输出”数据，输入数据是指决策单元在某种活动中需要消耗的某些量，例如投入的资金总额，投入的总劳动力数，占地面积等等；输出数据是决策单元经过一定的输入之后，产生的表明该活动成效的某些信息量，例如不同类型的产品数量，产品的质量，经济效益等等．再具体些说，譬如在评价某城市的高等学校时，输入可以是学校的全年的资金，教职员工的总人数，教学用房的总面积，各类职称的教师人数等等；输出可以是培养博士研究生的人数，硕士研究生的人数，大学生的人数，学生的质量（德，智，体），教师的教学工作量，学校的科研成果（数量与质量)等等．根据输入数据和输出数据来评价决策单元的优劣，即所谓评价部门（或单位）间的相对有效性．(In people s productive activities and social activities often encounter such a problem: After a period of time, need to have the same type of departments or units (referred to as the decision-making unit) to evaluate the basis for his assessment in decision-making unit "input "Data and" output "data, input data refers to the decision-making unit in certain activities that need to consume certain amount of, for example, the total funds invested, the investment of the total workforce number, area, etc. output data through the decision-making unit After a certain input to produce the show the effectiveness of the activity of certain amount of information, such as different types of product quantity, product quality, economic efficiency and so on. Be more specific, said, for example, in evaluating a city s institutions of higher learning, the input can be the year the school funds, the total number of faculty, teaching a total area of space, all kinds of titles the number of teachers, etc)

现代编码调制作业，不同信噪比下的信道容量计算(Modern coding and modulation operations, different SNR channel capacity calculation)

说明：  利用matlab对平平腔中自在现模的进行了模拟(Using matlab to the flat itself is in the mold cavity has been simulated)

首先录入一段音频，在通过matlab软件对该音频进行处理，识别出他的波峰波谷，频率变换，然后输出。(First, an audio input, matlab software through the audio processing, identify the peaks and valleys of his, frequency conversion, and output.)

This simulation file is in matlab software and is about the pwm closed loop chopper.

调用line（）函数与plot（）函数，运用for循环命令。 线宽5，线条颜色为黑色，填充颜色与线条颜色不同。 坐标轴取等长刻度，标题：正五角星，x轴、y轴加上标注。(Calling line () function with the plot () function, use a for loop command. 5 width, line color is black, filled with color and line color is different. Take the long axis scale, etc., Title: Positive pentagram, x-axis, y-axis plus mark.)
