中文说明：雅克比迭代求解线性方程组课设,这个有中文注释，看得明白，包括最后计算压缩图像的峰值信噪比和压缩效果的源码,计算目标和海洋回波的功率谱密度,结合PCA的尺度不变特征变换(SIFT)算法，已经调试成功.内含m文件，可直接运行。
English Description：
Jacobi iteration for solving linear equation group lessons, the Chinese notes, to understand it, including finally calculated compression image peak signal-to-noise ratio and compression effect of the source code, computed power spectral density of the target and sea echo, combined with PCA scale invariant feature transform (SIFT) algorithm, has been successful debugging. Contains M documents, can be directly run.
