PCA-KPCA

对于Ldpc码，测试其校验矩阵H有无4环的存在，避免因为存在4环影响性能(For Ldpc code, test whether the check matrix H of the existence of loop 4, loop 4 to avoid because of the impact of performance)

FDTM code for square area

说明：  数据降维工具箱，包括一些典型算法，例如pca，lle，mds，lda等。(Data dimension reduction toolbox, including some typical algorithms, such as PCA, LLE, MDS, LDA, etc.)

full wave rectifierDuring the period from 伪 to 蟺, the input voltage vs input current is are positive and the power flows from supply to the load. The converter is said to be operated at rectification mode .During the period from 蟺 to 蟺+伪 , the input voltage vs is negative and the input current is is positive and reverse power flows from load to the supply. The converter is said to be operated in inversion mode. Depending on the value of 伪, average output voltage can be either positive or negative and hence provides 2 quadrant operation.
