A High Pass filter matlab code for image processing in frequency domain

Backpropagation, an abbreviation for backward propagation of errors , is a common method of training artificial neural networks used in conjunction with an optimization method such as gradient descent. The method calculates the gradient of a loss function with respects to all the weights in the network.

自己写的频率谱细化程序，应用了两种方法实现，经过测试效果不错，拿来和大家分享。(there are two programs that make the Zoom_fft come true.)

dft 的matlab仿真，以及仿真结果 图片以及必要的文字描述(the simulation of the DFT under matlab circumstance)

获取理想频段内的信号，这样就有助于进行相应的信号处理工作(The ideal band for the signal, so that helps to make the appropriate signal processing)

系统功率联合分配的matlab仿真算法,提高系统性能(Joint distribution power system matlab simulation algorithm)
