fft_DIF_R2_eML

说明：  数学建模中的图论知识来研究最短路径的问题，利用Dijkstra算法matlab实现(Graph theory knowledge in mathematical modeling is used to study the shortest path problem, which is realized by using Dijkstra algorithm matlab.)

programmed to manipulate the Gray Cyclic Binary Codes.

CML for block turbo coding

说明：  独立成分分析算法降低原始数据噪声，并提取特征值，非常有用得数据去噪程序。(Independent component analysis algorithm reduces the raw data noise, and extract characteristic value, is more helpful data denoising procedure.)

This demo tracks cars in a video by detecting motion using optical flow. The cars are segmented from the background by thresholding the motion vector magnitudes. Then, blob analysis is used to identify the cars.

北工商Matlab课件，对初学者很有用；用Matlab解方程的程序源代码以及有限差分方程源代码，希望对学习Matlab的小朋友有帮助(North Business Matlab courseware, useful for beginners with Matlab equations for the source code and the finite difference equation is the code, hope to help children learn Matlab)
