代码说明:

说明:  目前的代码是一个matlab函数,它提供给定信号x[n]的短时傅立叶变换(stft)。该函数是matlab命令“光谱图”的一个替代项。功能输出为: 1)一个具有复杂stft系数的矩阵,该矩阵具有跨列时间和跨行频率; 2)频率矢量; 3)时间矢量。 为了阐明函数的用法,给出了一个示例。为了方便起见,输入和输出参数在函数的开头给出。(The present code is a Matlab function that provides a Short-Time Fourier Transform (STFT) of a given signal x[n]. The function is an alternative of the Matlab command spectrogram The output of the function is 1) a matrix with the complex STFT coefficients with time across the columns and frequency across the rows; 2) a frequency vector; 3) a time vector. An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.)

  • 基于LS-DYNA的Lagrange网格与SPH鸟撞分析对比研究
    说明:  别采用La酽蚰ge网格和SPH(SmoothedPalticleHyd功dyn啪ics,光滑粒子流体动力学法)模拟鸟体 进行风挡抗鸟撞性能对比分析,表明SPH分析得出的结果与传统的h鲫ge网格方法得出的结果以及试验实测 结果基本一致,为分析动力学大变形问题提供了更多的途径。(The results are basically consistent, which provides more ways for the analysis of dynamic large deformation problems.)

  • MQTT协议中文版
    MQTT协议 3.1.1中文版 MQTT是一个客户端服务端架构的发布/订阅模式的消息传输协议。它的设计思想是轻巧、开放、简单、规范,因此易于实现。这些特点使得它对很多场景来说都是很好的选择,包括受限的环境如机器与机器的通信(M2M)以及物联网环境(IoT),这些场景要求很小的代码封装或者网络带宽非常昂贵。(MQTT is a messaging protocol in publish/subscribe mode of client server architecture. Its design idea is lightweight, open, simple and standardized, so it is easy to implement. These features make it a good choice for many scenarios, including limited environments such as machine-to-machine communication (M2M) and Internet of Things (IoT), which require very small code encapsulation or very expensive network bandwidth)
