功率谱估计，通过matlab程序对声发射信号进行功率谱估计(Power spectrum estimation, through the matlab program to acoustic emission signals, power spectrum estimation)

一般的esprit算法好的时间比较大，在计算子空间是算法比较烦，我改了一些矩阵算法。(general esprit algorithm good time, the calculation algorithm is a subspace trouble, I changed some matrix algorithm.)

The objective is to measure the differences between two images, and measurement of image quality.

omp 算法 你可以通过这个算法完成图像恢复，效果好，恢复时间短，误码率低，解决凸优化算法复杂度高的缺点convex optimization algorithm with high complexity(omp algorithm you can accomplish by this algorithm for image restoration, good effect, shorter recovery time, error rate, to solve the shortcomings of convex optimization algorithm with high complexity)

After we calculate the R peaks of the ecg signal, we identify different criteria : a) Heart rate. b) Regularity of the R-R peaks (Look at the R-R distances). 1. Regular (are they equidistant apart). 2. Irregular. c) Rhythm 1. Tachycardia ==> Fast. 2. Bradychardia ==> Slow. 3. Normal.
