If A^(T) is the transpose of a square matrix A, then
If A is a skew symmetric matrix of order n and C is a column matrix of order nxx1 ,then C^(T)AC is
Matrix A ha s m rows and n+ 5 columns; matrix B has m rows and 11 - n columns. If both AB and BA exist, then (A) AB and BA are square matrix (B) AB and BA are of order 8 xx 8 and 3 xx 13 , respectively (C) AB=BA (D) None of these
If X is a non-zero column matrix, such that A X=lambda X where lambda is a scalar and the matrix A is [[4,6,6],[1,3,2],[-1,-5,-2]] then sum of distinct values of lambda is
