Matlab-ODE--PPT

自相关虽然能够判断清/浊音，并估计浊音的基音周期，但是其运算量很大，用乘法运算所需时间较长。为了避免乘法，采用短时平均幅度差函数（AMDF），验证AMDF与自相关有类似的作用，即平均幅度差函数能够代替自相关函数进行语音分析。(Although autocorrelation can differ from the Voiced/Unvoiced and voiced the pitch period estimate, but the operation is large enough, with the multiplication time was needed. In order to avoid the multiplication using the short time average magnitude difference function (AMDF), verify the AMDF and autocorrelation have a similar effect, that the average magnitude difference function can replace the voice of the autocorrelation function.)

matlab编制的电力系统暂态稳定分析程序， 可计算潮流，机电暂态仿真。带算例，有说明书，鲁汶大学编制(MatDyn is a free Matlab based open source program to perform dynamic analysis of electric power systems. It is inspired by MATPOWER, a power flow and optimal power flow program in Matlab and shares its philosophy: “It is intended as a simulation tool for researchers and educators that is easy to use and modify.” [1]. The source code of MatDyn is available. Care has been taken to keep it well structured and easy to understand.)
