实现wf功能，matlab源程序(Wf realize functions, matlab source)

matlab编程进行离心叶轮一维初始参数计算(matlab programming centrifugal impeller one-dimensional initial parameter calculation)

可以做出一个漂亮的三维心形，赶快快来试试吧(Can make a beautiful three-dimensional heart-shaped, come try it)

Three-Phase Three-Level PWM Converter This demonstration illustrates simulation of a three-phase, three-level inverter and discrete three-phase PWM generator. It also demonstrates harmonic analysis of PWM waveforms using the Powergui/FFT tool

In this paper, the concepts of Daubechies wavelet transform are discussed. The Daubechies wavelets are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for some given support. With each wavelet type of this class, there is a scaling function which generates an orthogonal multi resolution analysis.

对EBPSK(Extended binary phase shift keying)调制雷达系统的特点，本文将其与传统的LFM(Linear frequency modulation)雷达系统进行综合性能比较。(he overall performances of EBPSK(Extended binary phase shift keying) modulation and LFM(Linear frequency modulation) radar systems are compared. First, the target detection performance base on CFAR(Constant False Alarm Rate) of two systems are analyzed under several conditions. As the time-delay is relatively large, the detection performance of EBPSK modulation radar system is better than LFM radar system. EBPSK modulation signals can combat the effect of Doppler spread on system performance in HF(High Frequency) channel.)
