Suppose that a matrix A is formed by taking n vectors from R^m as its columns.
a) if these vectors are linearly independent, what is the rank of A and what is the relationship between m and n?
is the rank the same as the dimension of the column space, or n, and m less than or equal to n?
b) if these vectors span R^m instead, what is the rank of A and what is the relationship between m and n?
is the rank m and m=n?
c) if these vectors form a basis for R^m, what is the relationship between m and n then?
is m=n?
