Transpose of a row matrix is
Two matrices A and B are multiplied to get AB if
If the order of matrix A is of 2X3 and B has 6 entries. If A and B are conformable for matrix multiplication then the order of AB is
Transpose of a rectangular matrix is a
A square matrix in which all elements except at least one element in diagonal are zeros is said to be a
Inverse of the product AB that is =
Idea of matrices was introduced by Arthur Cayley in
If A(BC) = (AB)C, then with respect to multilpication this law is called
In Matrix algebra additive identity is
Matrices obtained by changing rows and columns is called
If A and B are matrices, then which from the following is true ?
If A is a symmetric matrix, then (that is transpose of A)
A matrix is rectangular array of
A matrix having m rows and n columns with m ≠ n is said to be a
[ a b c ] is a
If A+B=O then B is called
Generally elements of a matrix are denoted by
If A= is a
The total no of matrices of order 3 by 3 where each element is either 7 or 11 is
If the order of matrix A is 2 X n and if B is a square matrix having 9 elements. The product AB exists. Then n=
