说明：  VC调用matlab，实现VC与matlab混合编程，效果很好(VC call matlab, matlab mixed programming with VC to achieve good results,)

利用matlab进行图形的二维傅里叶变换(Using matlab graphical two-dimensional Fourier transform)

生物医学信号处理是以数字信号处理为基础的离散信号及 离散系统的研究，因此．其预算过程基本上都是卷积或者相关预 算。在MATLAB中可以很容易实现这种运算。(Biomedical signal processing is based on digital signal processing discrete signals and discrete systems research, therefore. The budget process is basically the convolution or related budget. In MATLAB, can easily achieve this operation.)

图像转换成二进制序列、二进制序列还原成图像MatlaB自编源代码(Image is converted into binary sequences, binary sequence to restore self-compiled source code into an image MatlaB)

概率神经网络的分类预测-基于PNN变压器故障诊断(Probabilistic neural network classification and prediction- PNN transformer fault diagnosis based on)

没有用工具箱的DCT变换，采用不同压缩率，能够加深对DCT变换的了解。(Do not use toolbox of DCT, using different compression ratios, to deepen understanding of the DCT transform.)

在图像精度评价中，主要用于比较分类结果和实际测得值，可以把分类结果的精度显示在一个混淆矩阵里面。混淆矩阵是通过将每个实测像元的位置和分类与分类图像中的相应位置和分类像比较计算的。(In the image to uate the accuracy, mainly for comparison of classification results and the actual measured value, the accuracy of the classification results are displayed in a confusion matrix inside. The confusion matrix is measured by each pixel position and image classification and classification in the appropriate location and classified as comparative calculations.)

锁相环实验，PLL参数测试，锁相环PLL原理与应用，环路滤波器 (The experimental phase-locked loop, PLL parameter testing, and application of the principle of the PLL loop filter )

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)
