- Show that the matrix below does not have an LU factorization. A=0110arrow_forward11. Find two nonzero matrices and such that.arrow_forwardIn general, it is difficult to show that two matrices are similar. However, if two similar matrices are diagonalizable, the task becomes easier. In Exercises 38-41, show that A and B are similar by showing that they are similar to the same diagonal matrix. Then find an invertible matrix P such that .arrow_forward
- Use an example chosen from 22 matrices to show that for nn matrices A and B,ABBA but AB=BA.arrow_forwardLet A be an nn matrix in which the entries of each row sum to zero. Find |A|.arrow_forwardConsider the matrices below. X=[1201],Y=[1032],Z=[3412],W=[3241] Find scalars a,b, and c such that W=aX+bY+cZ. Show that there do not exist scalars a and b such that Z=aX+bY. Show that if aX+bY+cZ=0, then a=b=c=0.arrow_forward
