代码说明:

  将系数矩阵A转变成等价两个矩阵L和U的乘积 ,其中L和U分别是下三角和上三角矩阵。当A的所有顺序主子式都不为0时,矩阵A可以唯一的分解为A=LU。其中L是单位下三角矩阵,U是上三角矩阵。 (The coefficient matrix A into two matrices L and U is equivalent to the product, where L and U are lower triangular and upper triangular matrix. When A master style is not all the sequence is 0, the matrix A can only be decomposed into A = LU. Where L is unit lower triangular matrix, U is upper triangular matrix.)

    DISTEU Function DISTEU Pairwise Euclidean distances between columns of two matrices Input: x, y: Two matrices whose each column is an a vector data. Output: d: Element d(i,j) will be the Euclidean distance between two column vectors X(:,i) and Y(:,j) Note: The Euclidean distance D between two vectors X and Y is: D = sum((x-y).^2).^0.5
