If you want to normalize the vector so that all its elements are between 0 and 1, you need to use the minimum and maximum value, which you can then use to denormalize again. %# generate some vector vec = randn(10,1); %# get max and min maxVec = max(vec); minVec = min(vec...
so that R'*R = X(1:q,1:q). When X is sparse, R is an upper triangular matrix of size q-by-n so that the L-shaped region of the first q rows and first q columns of R'*R agree with those of X. 2. LU分解(LU factorization). 用lu函数完成LU分解,将矩阵分解为上下两个三角阵...
