Matlab基本电路运算，只需要输入电路的基本信息如节点数，电源的电压。电流等即可得出电路所有的电量(Matlab basic circuit operation, and only need basic information such as the number of nodes of the input circuit, the power supply voltage. Current, etc. can draw all the power of the circuit)

说明：  小波阈值去噪的基本思想是先设置一个临界阈值λ，若小波系数小于λ，认为该系数主要由噪声引起，去除这部分系数;若小波系数大于λ，则认为此系数主要是由信号引起，保留这部分系数，然后对处理后的小波系数进行小波逆变换得到去噪后的信号。(The basic idea of wavelet threshold denoising is to set a threshold value of lambda first. If the wavelet coefficient is less than lambda, it is considered that the coefficient is mainly caused by noise and this part of the coefficient is removed. If the wavelet coefficient is larger than lambda, it is considered that the coefficient is mainly caused by signal, and this part of the coefficient is retained. Then the denoised signal is obtained by inverse wavelet transform of the processed wavelet coefficient.)

通过一点来选取图像区域，手动选取图像中的一点，可以讲这个点周围的一定区域提取出来(Through a point to the image area，manual one point in a image，then we can get an area around this point)
