The matlab source code about SIFT algorithm with Accurate Key locations.

说明：  用最速下降法、共轭梯度法、牛顿法、BFGS求解范例目标函数.(Solving the case objective functions using the steepest descent method, conjugate gradient method, Newton method and BFGS method.)

说明：  这是基于周期图改进的welch的功率谱估计，这种方法是在经典周期图的基础上改进而来的，效果很不错(This is based on the improved welch periodogram power spectral estimation, this method is based on the classical periodogram improvement came, the effect is very good)

This particular code very useful to simulate the antenna array design and very effective

金融时间数列的基本处理程序代码和函数使用实例(Examples of financial time series basic handler code and function)

单一螺旋线与平面交点个数的算法问题。从不同情况下计算了交点个数。(Single spiral plane intersection of the number of algorithmic problems. From the intersection number is calculated under different conditions.)

求传递函数的一般格式，通过该程序，我们基本上能写出求任意的传递函数的式子(The general format of the transfer function of demand。Through this program, we can write the formula basically seeking arbitrary transfer function)

This is a MATLAB code which provides the performance of a cyclic code.

说明：  该程序实现OFDM系统中块状导频的信道估计，块状导频用于时变较慢的多径信道，可以估计出每个载波上的信道传输情况。(The programme realizes channel estimation with block pilots.)

说明：  自己在编matlab C语言模块时的一些总结(Some of my experiences about matlab s C SFunction)
