Web9 apr. 2024 · Properties of the Rank of the Matrix: Rank linear algebra refers to finding column rank or row rank collectively known as the rank of the matrix. Zero matrices have no non-zero row. Hence it has an independent row (or column). So, the rank of the zero matrices is zero. When the rank equals the smallest dimension it is called the full rank … Web25 jul. 2016 · The matrix has one linearly independent row (take the negative of the second to get the third) implying that the rank is 1 and the nullity is 2.
