脑电信号处理所用的TOOLBOX,MATLAB-Based Tools for BCI Research(BRAIN WAVE BCI)

费希尔线性判别分析代码 Find the Fisher linear separator w (a column vector). X is is the training set (X is a matrix. Each row of X is a vector containing the features of a single sample). y is a column vector with the labels of the training set (1 and -1). alg is a number between 1 and 3 that specifies how to find w: alg = 1: w is the generalized eigenvalue of A,B. alg = 2: w is the solution to Bw = (mu_1-mu_2) alg = 3: solve the corresponding regression problem( Find the Fisher linear separator w (a column vector).

说明：  有效观察OAM的相位模式，可自由设定拓扑荷数(Observing the phase mode of OAM effectively, the topological charge can be set freely.)

数字信号处理用的快速傅里叶变化，可提供分段，复盖（Overlap)，时程图，频谱图。(digital signal processing using Fast Fourier changes, can provide sub-covering (Overlap) time- and frequency spectrum.)

PcA和Fisher方法的人脸识别,希望对大家有用，(PcA Fisher and methods of face recognition, we hope to useful,)
