一个利用半正定规划求解 SDE/MVU 非线性数据降维的算法实现，这是论文原作者提供的 MATLAB 代码。(A MATLAB implementation of the Semi-Definite Embedding (SDE) or namely Maximum Variance Unfolding (MVU) algorithm, provided by the author himself.)

One of the most popular measurements of an ECG signal is the heart rate in this function we describes how to extract the R peak of a signal in order to analyze them in the "Regularity_Rythm" Function. The peak with the highest amplitude is called the R wave. An RR interval is the time that elapses between two successive R waves.

Nonuniform mesh semivector: Illustrates usage of the semivector modesolver to calculate the quasi-TE and quasi-TM modes of a ridge waveguide. Use the stretchmesh function to expand the size of the computation window at the edges without increasing the number of gridpoints.
