基于Matlab的系统信号FFT频谱分析与显示(System based on Matlab Signal FFT spectrum analysis and display)

说明：  灰度直方图显示，不使用MATLAB中自带的程序，直接编写得到(Histogram display, do not use the built MATLAB program, prepared by directly)

前推回代法编的39节点40条支路的潮流计算程序。对于研究电力系统潮流计算有一定帮助！(Forward and backward substitution method series of 39 nodes 40 branch flow calculation procedures. Power flow calculation for the study of some help!)

This m-file implements a simple data acquisition gui with multiple channels and custom triggering It demonstrates how to: 1) Use nested functions to simplify data acquisition programs 2) Use a simple GUI (a couple of pushbuttons) to start and stop data acquisition. 3) Wait for an event/trigger (like a button press) and log pre-event or pre-trigger data from multiple synchronized channels. 4) Record pretrigger data based on custom criteria. In this m-file the triggering event is a button click. However, the event could be any custom criterion (e.g., the data amplitude is greater than a threshold *and* a toggle button is enabled). Requires: the Data Acquisition Toolbox (TM) and the Winsound adapter. It does not depend on any hardware-specific capabilities.
