so , Such a matrix is of the form [0 b] [c 0] for some b, c. Since these matrices are generated by [0 1].[0 0] [0 0],[1 0], the dimension equals 2. is that a right answer ?

Find the dimension of the subspace of M2;2 consisting of all 2 by 2 matrices whose diagonal entries are zero. ? i know that the dimension is the number of vectors that are the basis for this subspace ,but i cannot figure out what is the basis for this subspace ? any help will be...

1)Determine whether the given statement is true or false. A homogeneous linear system with the same number of equations as unknowns always has a unique solution. 2)Determine whether the given statement is true or false. If a linear system has no solution, the rank of the coecient matrix...
