The row rank of a matrix is the maximum number of rows, thought of as vectors, which are Linear independence - Wikipedia. Similarly, the column rank is the maximum number of columns which are linearly indepen- dent. It is an important result, not too hard to show that the row and column ranks of a matrix are equal to each other.

In linear algebra, the rank of a matrix A is the dimension of the vector space generated (or spanned) by its columns. This corresponds to the maximal number of linearly independent columns of A. This, in turn, is identical to the dimension of the vector space spanned by its rows. Rank is thus a measure of the "nondegenerateness" of the system of linear equations and linear transformation encoded by A. There are multiple equivalent definitions of rank.
