MATRICES
TYPES OF MATRICES:
1) Zero matrix
2) Square matrix
Mmxn , the number of rows m is equal to the number of columns n
3) Identity matrix
Is a square matrix + it has Maa=1 and Mbb=0
4) Diagonal matrix
Is a square matrix + Mab=0
Example:
, 5) Upper triangular matrix
Is a square matrix + Mab=0 below the diagonal
6) Lower triangular matrix
Is a square matrix + Mab=0 above the diagonal
7) Symmetric matrix
Is a square matrix and Mab=Mba
8) Antisymmetric matrix
Is a square matrix + Mab=-Mba and Maa=0
MATRIX ADDITION :
Note: you can NOT add two matrices unless they have the
same dimensions
