Calculating Rank and Nullity
The rank and nullity of a matrix can be calculated using the following steps:
Row Reduction: Reduce the matrix to its row-reduced echelon form (RREF) using elementary row operations.
Counting Linearly Independent Vectors: Rank of a matrix is the number of linearly independent row or column vectors in the RREF.
Calculating Nullity: Nullity of a matrix is calculated by subtracting its rank from the total number of columns in the matrix.
Rank and Nullity
Rank and Nullity are essential concepts in linear algebra, particularly in the context of matrices and linear transformations. They help describe the number of linearly independent vectors and the dimension of the kernel of a linear mapping.
In this article, we will learn what Rank and Nullity, the Rank-Nullity Theorem, and their applications, advantages, and limitations.
