where B is a m×nm×n , C is a m×km×k , D is a k×nk×n and E is a k×kk×k matrix. If E is an invertible matrix, what can we say about rank(A)?I just know that the rank of a matrix is equal to the maximum number of linearly independent rows (or columns). I ...
FAQ: Linear Algebra : Rank of a matrix What is the rank of a matrix? The rank of a matrix is the maximum number of linearly independent rows or columns in the matrix. In other words, it is the dimension of the vector space spanned by the rows or columns of the matrix. How is ...
8.1 Linear Subspaces A linear subspace of a vector space is a subset of the vectors that is itself a linear space. To show that a subset of a linear space is a linear subspace one only has to check three things. This is captured by the following theorem. Theorem 8.1: Let V be a...
