T型尾翼颤振进计算。结合了nastran生成的模态坐标f06文件及气弹计算软件ZAERO。片条法计算非定常气动力里面的定常附加部分。(T-tail flutter ansys, composite of f06 and ZAERO.)

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).
