脉冲宽度调制（PWM）是英文“Pulse Width Modulation”的缩写，简称脉宽调制。它是利用微处理器的数字输出来对模拟电路进行控制的一种非常有效的技术，广泛应用于测量，通信，功率控制与变换等许多领域。一种模拟控制方式，根据相应载荷的变化来调制晶体管栅极或基极的偏置，来实现开关稳压电源输出晶 体管或晶体管导通时间的改变，这种方式能使电源的输出电压在工作条件变化时保持恒定。　　脉冲宽 (Pulse width modulation (PWM) is the English " Pulse Width Modulation" acronym, or pulse width modulation. It is the use of the microprocessor to the digital output of analog circuits for the control of a very effective technology, widely used in measurement, communications, power control and many other fields with the transformation. An analog control means, in accordance with the corresponding changes in load modulation transistor gate or base bias, switching power supply to achieve the output transistors or transistor on-time changes in power in this way can the output voltage in the workplace conditions of constant change.

ADC动态性能测试，包括FFT法，正弦拟合法，直方图法，还可以测试通道之间一致性(ADC test of dynamic performance,including FFT method,sine fit method,hist method etc.)

functions not separated by semicolons are errors in version 120 and higher.

在矩阵或者二维图像中画一个圆,没有丢失的像素点 (Draw a circle in a matrix/image)

在matlab中，gui中在图像上鼠标移动时可以获取坐标。(Image in matlab, gui mouse movement can get the coordinates.)

这本书关注成像问题，是非常独特的竞争中书逆和病态问题。很好的引入MATLAB的图像和去模糊问题，适合图像处理和模糊理论的学者学习(Deblurring Images: Matrices, Spectra, and Filtering)
