Matlab

编码，交织，编纂和调制的GSM信道仿真。具有一定得应用价值(have something)

潮流程序 IEEE-9 IEEE-30 已验证(The powerflow program. IEEE-9 IEEE-30 Verified)

signal and ssystem matlab function change inverse fourier transfom frequency domain to time domain

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

四、软件的功能 1、核算结算成本 2、稽核县局收入 3、统计六网的收入和成本 4、核算利润率 5、统计客户经理业绩(4, the software features a, accounting settlement cost of the two, the auditing county bureau of income 3, Statistics 6 net revenue and cost four, accounting profit margin of 5, statistical account manager performance)

matlab上通过GUI实现神经网络的实例(GUI netural network experiment.)

画出下述情况下均匀线阵方向图 1）计算来波方向为0度方向图 2）画出来波方向为45度时的方向图 3）画出来波方向为0度，幅度取分贝数：20log***（单位为dB）时的方向图 4）画出来波方向为0度，随着阵元数的增加，当N=16，N=32时的方向图，并对方向图的变化情况进行说明(Draw the following conditions uniform linear array 1) calculation of wave direction is 0 degrees direction diagram 2) draw out the wave direction is 45 degrees direction map 3) draw out the wave direction is 0 degrees, and amplitude decibels: 20log*** (unit dB) when the direction of FIG. 4) draw out the wave direction is 0 degrees, with the increase of the number of array elements, when N=16, N=32 pattern, and the change of direction is described )

this system is for display the ecg signal
