Either a string naming a function that calculates the gradient, or the null matrix

绘出余弦的16个点的傅立叶变化图，你可以在程序中改变点的个数，得到你想要的图形(Draw the 16-point cosine Fourier map changes, you can change in the program the number of points to get the graphic you want)

关于matlab中simulink编程建模，研究有指导意义，对初学者有帮助(Matlab simulink programming modeling research guidance, help for beginners)

对二维结构进行拓扑优化，基于变密度法的二维mbb梁的结构拓扑优化，迭代采用优化准则法，数值不稳定采用灵敏度过滤法。(Two-dimensional structure topology optimization, based on the variable density method of two-dimensional the MBB beam structure topology optimization, iterative optimization criteria, the numerical instability sensitivity filtration.)

某火箭在空中沿直线做匀加速飞行，加速度为 ，发动机推力的波动一定会引起加速度波动，雷达以间隔时间不断测量该火箭距离远点的距离 ，由于雷达的测量噪声使得火箭距离测量值 中含有噪声。现在欲通过雷达对火箭距离的测量数据求得火箭的真实距离、速度和加速度。(A linear constant acceleration rocket flight in the air along the acceleration, the engine thrust fluctuation will cause the fluctuation of acceleration time interval measurement, radar to constantly the rocket from the far point of the distance, because the noise radar makes the rocket range measurements with noise. Now, the real distance, velocity and acceleration of the rocket are obtained by measuring the distance of the rocket by radar.)
