基于二维图像进行三维重建效果还可以，经测试误差较大(Two dimensional image reconstruction effect is also can be based on, after testing error)

BFGS算法: 可以解决无约束的最优化问题，如求目标函数的极值等。(BFGS algorithm: can solve unconstrained optimization problems, such as seeking the extreme, such as the objective function.)

采用解调分析方法，从信号中提取调制信息，分析其强度和频次就可以判断研究对象（诸如机械零件）损伤的程度和部位。(Using the demodulation method, the modulation information is extracted from the signal, the strength and frequency analysis can determine the study (such as mechanical parts) and location of the degree of damage.)

运用FFT技术来综合和分析电话拨号的过程，matlab来分解了这一过程，希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing The dual tone multi-frequency (DTMF) standard specifies that the tone generated by a button on a telephone key pad is the sum of two sinusoids, with frequencies determined by the button s row and column. The dial pad on the upper left allows you to select buttons and generate the corresponding tones. The signal plotted on the upper right is a recording of the FAX number for the MathWorks being dialed. You can replay the entire signal, or select individual segments. The power plot is the magnitude of the FFT of the signal being played. What is the MathWorks FAX number?)
