金融时间序列data，著名的那本书的data (datafdfjkajfkd AIVAFDF)

matlab mdl 的卡尔曼滤波程序清晰简洁(matlab mdl Kalman filtering procedures clear and concise)

matlab实现用双线性插值法放大和缩小图像(Zooming and Shrinking Images by Bilinear Interpolation (a) Write a computer program capable of zooming and shrinking an image by bilinear interpolation. The input to your program is the desired size of the resulting image in the horizontal and vertical direction. You may ignore aliasing effects. (b) Download Fig. 2.19(a) and use your program to shrink this image 1024 x 1024 to 256 x 256 pixels. (c) Use your program to zoom the image in (b) back to 1024 x 1024. Explain the reasons for their differences. )
