Obviously the zero matrix always has rank 0. For any n x n matrix, the rank is n if and only if the determinant is non-zero. But for a 3x3 matrix, if the determinant is zero, you only know the rank isn't 3 (and isn't 0 if it's not the zero matrix). You still need to work out if the rank is 1 or 2. It will be rank 1 iff all 3 rows of the matrix ...

What I really want to do is create a loop that chooses a different set of three rows each time, and calculates the rank each time, until I find a set of three rows where the rank of my matrix Y is some arbitrary value z. Finally, I want the loop to finish and tell me which rows were used to create Y that gave a rank of z. Is this possible?

Nov 11, 2009 · and nullity is the number of rows minus the rank. finally to find the basis of the nullspace we use the reduced matrix and then consider a vector x = (x1, x2, x3, x4) and solve ref(A)x=0 the dependent variables for the independant and so you get the vectors which constitute the basis of the nullspace. hope this helps

Since A 2 = A, we know that for a matrix , a = a 2 + bc. b = ab + bd, so b – ab – bd = 0 and b (1 – a – d) = 0 and either b = 0 or d = 1 – a. c = ca + cd, so c – ca – cd = 0 and c (1 – a – d) = 0 and either c = 0 or d = 1 – a. d = bc + d 2. To come up with your own idempotent matrix, start by choosing any value of a.
