(1)
m*n
Let A屬於R and R be its reduced row echelon form.Then there
is a unique invertible m*m matrix P such that P such that PA=R.
F:P不是唯一嗎? 為什麼錯....
可以參考一下17503&17505 我有問一題是類似的
那題有說是sequence 那有很多種，我ok，但最後的
P不是唯一嗎QQ
(2)
Let A be a real-valued n*n matrix .If A is nonsingular,then there exists
a matrix B that is similar to A.
T:相似跟矩陣可逆有關係嗎?? 有什麼證法嗎?
