本程序为捷联惯导的解算程序(由惯性器件的输出解算出飞行器的位置、速度、姿态信息)和GPS的卡尔曼滤波程序(INS and GPS Kalman Filter)

邻域平均法滤波 原图像画面清晰，添加勒椒盐噪声后图像上产生勒明显的黑色斑点（噪声），用不同模板的平滑滤波处理后图像上的噪声消失，但是图像变得模糊，并且，使用的模板越大，对图像的去噪效果越好，同时图像也变得越模糊。 (Neighborhood averaging filter clear picture of the original image, add the Le Salt and pepper noise generated after the image Roming noticeable black spots (noise), smoothing with different template processed image noise disappear, but the images become blurred, and the use of template bigger the better the image de-noising the same time, the image becomes more blurred.)

this matlab code is of interpolation of some given points using newton s divided difference method.
