Row space
In computer science and mathematics, the row space of an m-by-n matrix with real entries is the subspace of Rn generated by the row vectors of the matrix. Its dimension is equal to the rank of the matrix and is at most min(m,n).
Given a matrix J:
and
r1 = (2,4,1,3,2),
r2 = (-1,-2,1,0,5),
r3 = (1,6,2,2,2),
r4 = (3,6,2,5,1)
The row space of J is the subspace of R5 spanned by { r1, r2, r3, r4 }
