WebJan 18, 2024 · The idea behind solving this problem is, First check traverse matrix and reach all diagonals elements (for principal diagonal i == j and secondary diagonal i+j = size_of_matrix-1) and compare diagonal element with min and max variable and take new min and max values. and same thing for secondary diagonals. Here is implementation of … Web1. Since the matrix is real and symmetric, it is diagonalizable. Since its rank is 1, we have an eigenvalue λ ≠ 0. The diagonalized matrix has λ on one component of the diagonal. All the other components of the diagonalized matrix are 0. So its trace is exaclty λ. By the invariance of the trace we have also that the trace of the starting ...
