说明：  matab实验讲义，呵呵 这是我收藏的学习资料(matab experiment handouts)

fft，本代码主要介绍fft的主要步骤，非常简单有很明了，非常适合阅读 (FFT, the code describes the main steps of FFT are very clear, very simple, very suitable for reading)

从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

捷联惯导方程矩阵在matlab环境下的仿真源代码程序(SINS matrix equation matlab source code under the simulation program)

uses the message signal X to modulate the carrier frequency Fc (Hz) and sample frequency Fs (Hz), where Fs > 2*Fc. FREQDEV (Hz) is the frequency deviation of the modulated signal.

Used to select common points on two images for morphing. Data saved as a *.mat file afterwards.(Used to select common points on two images for morphing. Data saved as a *.mat file afterwards.)

stc算法，主要用于地震勘探领域，利用接收器接收到的波形信号求取速度(STC meithod, used for calculation of velocity)

给定栅格图象及其变形后的栅格图象，请你首先确定各栅格交叉点的位移，然后采用控制栅格的方法编写实现图象几何校正的程序(Given raster images and raster images after deformation, you first determine the grid cross-point displacement, and then using the control method of preparation of raster realize image geometric correction procedures)
