[理工] 線代 找nullity
An n*n tridiagonal matrix.
Let V be the vector space of all n*n real tridiagonal matrices
under the operations of matrix addition
and multiplication of a matrix by a real number,
and T:V -> V be the linear operator defined by T(A)=(A+A^T)/2
for all A in V. Find the nullity.
------------------------------------------
我覺得是n-2
但是周易的解答寫n-1
麻煩大家為我解惑
謝謝
