Eigen Values of a skew Symmetric Matrix
The eigen values of a skew-symmetric matrix are (a) Always zero (c) Either zero or pure imaginary (b) always pure imaginary (d) always real if a matrix is skew symmetric then the elements in diagonal should be zero. A= |0 q| |r 0| Now solving for k ... get q=0, r=0, how does this tell us about the eigen values k PS: can't use lambda, so im using k here
