matlab下的万年历（没有利用自带函数）能够正确显示用户输入的年份和月份的日历。并能够自动定位当前年份和月份(Calendar matlab under (no use of its own function) to display the correct user input month and year calendar. And the ability to automatically locate the current year and month)

三相背靠背交流直流交流simulink仿真模型，采用PWM调制，电压闭环控制(VSC1 controls DC link voltage (Vdc 680 V)and VSC power factor on 60 Hz grid (PF 1.0)PWM frequency 33*60 1980 Hz VSC2 controls load voltage (VLL 380 Vrms 50 Hz) PWM frequency 2000 Hz )

This a WLS meshfree code have been developed for curve fitting problems. this archive contains Matlab subroutines

用Arnold矩阵变换进行图像置乱的加密算法及其源代码(By Arnold transform the matrix of image scrambling encryption algorithm and its source code)

模拟正弦衍射光栅光强分布，图1中X轴是位置，Y轴是光强，图2，是强度分布(Analog sinusoidal diffraction grating intensity distribution)
