minor在经济学里面的数学含义是什么?
例如,matrix对应的经济学数学里面的含义是矩阵,那么minor是什么呢?
Minors
The minor[Mij]of matrix A is the determinant of the matrix when row i and column i have been deleted.
For example,if the first row and first column are deleted from matrix
a11 a12 a13
A=a21 a22 a23
a31 a32 a33
the determinant of the remaining matrix will be the minor
a22 a23
[M11]=a32 a33

较小的矩阵,也就是在原矩阵里划去几行几列所剩下的那个矩阵
