positive matrices

F class generalized M-matrices include not only all M-matrices but also all positive matrices.

F型广义M-矩阵不仅包括了M-矩阵，还包括了所有的正矩阵。

On the other hand, square roots of semi-positive matrices can be expressed by the symmetric expression of eigenvalues, if the eigenvalues of semi-matrices are difficult to compute.

当特征根难以求出而特征根的对称式易求时，半正定矩阵的算术平方根可直接由矩阵的本身的性质来表示。
