无约束多维极值优化问题，这里提供算法，供大家参考(Multidimensional global optimization problems without constraint, provided here algorithm, for your reference)

说明：  1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图 (1. Using Matlab generated sine wave, rectangular wave, as well as the white noise signal, and display their respective time-domain waveform of Figure 2. FFT to transform, showing their frequency spectrum, including sampling rate, frequency, data length of 3-on-demand. Made of the three signals in root-mean-square maps, power maps, as well as the number of root-mean-square map 4. Fourier Transform IFFT with the restoration of signals, and displays the sinusoidal signal the resumption of time-domain waveform)

滑模控制 目标轨迹跟踪 源代码，对初学者很有帮助(Sliding mode control target tracking source code)

有限元分析优化，主要基于水平集方法，comsol的二次matlab开发(Finite element analysis and optimization, mainly based on the level set method, comsol matlab development of secondary)
