用于LFM的分析与生成，可用于仿真雷达信号等 1772Echo_signal_LFM

这个程序可用来画R(D)函数，学习信息论的一般要做这个。(This procedure can be used to draw R (D) function, learning the general information theory to do this.)

介绍了原型滤波器的设计，并比较了不同混叠因子下滤波器的性能(this code include the design of the prototype filter,which is widely used in the multicarrier communication.we also compare the performance with different coefficient.)

已知门诊时间C[i,3] 求解病人住院时间,此算法虽然有一定的局限行，但是可以根据入院期望值计算出来大体的的入院时间；使用是，要把里面的数据进行处理（只改变输入值和u 数据个数定义值（一般取较大值即可））(Known patient time C [i, 3] to solve the patient length of stay, although this algorithm has some limitations line, but expectations can be calculated according to the general hospital of admission time use is necessary to process the data inside (only change the number of input values ​ ​ and u define the data value (whichever is greater value to the general)))

针对变压器的故障诊断，通过概率神经网络对其进行分类。运行程序后，网络输出值和实际值非常接近，很好的实现了对变压器的故障分类。(For the transformer fault diagnosis, we use the probability neural network to classify it. After running the program, the network output value and the actual value is very close, which achieves the good classification of transformer fault .)

今天上传《数学实验与Matlab》2程序，希望对大家有用！谢谢！！！（(today uploaded "Matlab mathematical experiment with the" two procedures in the hope that it may be useful right! Thank you! ! ! ()

信号分析仪程序是有效的结合matlab语言与信号分析，形象直观的对所需分析的信号进行分析。(Signal analyzer matlab program is an effective combination of language and signal analysis, image analysis of visual signals to the required analysis.)

选取了民歌，古筝，摇滚和流行不同音乐，用神经网络对其进行有效分类。(Different from folk songs, guzheng, rock and pop music, using neural network to classification effectively.)

设计了各种窗函数的滤波器，包括矩形窗，滚降升余弦窗，切比雪夫窗，凯泽窗等。(Designed a variety of window function filters, including the rectangular window, roll-off raised cosine window, Chebyshev windows, Kaiser windows.)
