The number of matrices with equal rows and columns are calledsquare matrices. Note:
in matrix
The second element is in the 1st row and 1st column.
The element 5 is in the 1st row and 2nd column.
The element 7 is in the 2nd row and 1st column.
-9 The element is in the 2nd row and 2nd column.
Therefore, we have:
aij, where i = j = rows and columns.
a11 = 2
a12 = 5
a21 = 7
22 = -9
We can construct a matrix according to a law-based training in various situations. For example, we build a matrix of order 3 x 3, following the direction ij = 3i + 2j.
We write the matrix given by B (ij) 4x4, so that i + j, where i = Jei - j, where i ≠ j.
