XX. Given matrices:
X = B = C =
X = X = [3], X = , G =
Dimension XX a matrix XX XXX order of the XXXXXX: row x XXXXXX
X : 2 x 4, B : 4 x X, C: 1 x 3, D : X x X, E : X x 1, F : X x 4, G : X x X
When XXXXXXX = rows in a XXXXXX, XX called a square XXXXXX.
XXX square XXXXXXXX are : D XXX X
XX XXX transpose of a XXXXXX XX XXXXX to the XXXXXX itself, the matrix is said to be symmetric.
XXXXXXXXX of a XXXXXX XX a matrix obtain by using XXX rows XX XXX XXXXXX as XXXXXX in XXX XXXXXXXXX matrix.
XXXX matrix X = [3] is XXXXXXXXX
XXXXXX B
XXXXXX X
A XXXXXX XXXXXX XX a XXXXXX consists XX a XXXXXX column. The XXXXXXXXX of a column matrix is rows x X
Column matrices XXX : E and F
X row matrix XX a matrix consists XX a XXXXXX row. The XXXXXXXXX XX a row matrix XX X x XXXXXXX
Row matrices are : C XXX E
XXXXXXXXX of a matrix is a matrix obtain XX using the rows of the matrix as XXXXXX in XXX XXXXXXXXX matrix.

Q3. XXXXX XXX matrices :
X = , X = , X = ,
D = , X =
X XXXXXX XXXXXX in which every element XXXXXX the principle XXXXXXXX XXXXXXXX XX zero, it is called a XXXXXXXX matrix.
XXX XXXXXXXX matrices XXX: XXXXXXXX C XXX E
Alower triangular XXXXXXXX XXX which contains XXX its XXX-zero elements in and below XXX main XXXXXXXX.
The lower XXXXXXXXXX matrix is : XXXX matrix B
Xupper triangular matrixis one XXXXX XXXXXXXX XXX its XXX-XXXX elements in XXX XXXXX XXX XXXX diagonal.
XXX lower XXXXXXXXXX XXXXXXXX are : XXXXXXXX A and X
