Rank of Matrix A = 2
Given:
Matrix A =
To find:
The rank of matrix A
Solution:
The Rank of Matrix
- The rank of matrix is the number of linearly independent rows or columns in a Matrix.
- In simple words it is explained as the number of non-zero rows or columns of a matrix
Finding Rank of Matrix
- To find a Rank of Matrix we need to convert given matrix into a Echelon Form by suitable elementary operations
like, , etc.
- Then the rank of matrix will be equals to number of non-zero rows or columns of a matrix
Here given matrix A =
As we can see that the matrix A is already in Echelon Form
then Rank of matrix = Number of non-zero rows or columns = 2
Therefore,
Rank of Matrix A = 2
