Problem set 1 (1)Show that ATA=AAT (A T A ≠ A A T ) in general. (Proof and demonstration.) \[ A^TA = AA^T \] #let's see a 2x2 matrix A <- matrix(c(1,-1,2,-2), nrow = 2, byrow = TRUE) A ## [,1] [,2] ## [1,] 1 -1 ## [2,] 2 -2 #let's find the tranpose of A, we called it A1 A1 <- t(A) A1 ## [,1] [,2] ## [1,] ...

Linear Algebra: Eigenvalues, Eigenvectors, Eigenspaces in Matrix
Problem set 1 What is the rank of the matrix A? \[\mathbf{A} = \begin{bmatrix}1 & 2 & 3 & 4 \\-1 & 0 & 1 &3 \\ 0 & 1 & -2 & 1 \\ 5 & 4 & -2 & -3\end{bmatrix} \\\] The rank of A is n, r (A) = n. how do we find the rank of A? We found the rank of A by finding the maximum numbers of independent row or number of linear independent column. (1), r_1 ...
