The rank of a matrix, denoted by \(\operatorname{Rank} A,\) is the dimension of the column space of \(A\). Since the pivot columns of \(A\) form a basis for \(\operatorname{Col} A,\) the rank of \(A\) is just the number of pivot columns in \(A\). Example. Determine the rank of the matrix The dimension of CS(A) is called the rank of A; rank(A) = dim CS(A). The dimension of NS(A) is called the nullity of A; null(A) = dim NS(A). So, r = rank(A) = dim CS(A) = # of pivot columns of A; q = null(A) = dim NS(A) = # of free variables and rank(A) + null(A) = r + q = n = # of columns of A: This last fact is called the Rank-Nullity Theorem.

The rank of a matrix is the dimension of the image of the linear transformation represented by the matrix. The image is the column space of the matrix, so the rank is 

The dimension of the row space is called the rank of the matrix A. Theorem 1 Elementary row operations do not change the row space of a matrix. Theorem 2 If a matrix A is in row echelon form, then the nonzero rows of A are linearly independent.

(2) The column rank of A is the number of linearly independent columns of the matrix considered as vectors in n dimensional space. Theorem 4.1 Let A be an n by

The rank of a matrix, denoted by Rank A, is the dimension of the column space of A. Since the pivot columns of A form a basis for Col A, the rank of A is just the number of pivot columns in A. If V is nite dimensional, then the dimension of V is the number of vectors in any basis for V; we writedim V for the dimension of V. The dimension of the trivial vector space f~0gis de ned to be 0.

Dimension is the number of vectors in any basis for the space to be spanned. (2.) Rank of a matrix is the dimension of the column space. Rank Theorem : If a matrix "A" has "n" columns, then dim Col A + dim Nul A = n and Rank A = dim Col A.
