Let A3×2 be a fixed matrix with a12 = a31 = 0, but with other entries non-zero. Define T : M3,2 → M3,2 by T(X) = A ◦ X (the Schur-Hadamard product of A and X). What is the range of T? What is the kernel of T? Therefore what is rank(T)? Explain your answers.

Question
Let A3×2 be a fixed matrix with a12 = a31 = 0, but
with other entries non-zero. Define T : M3,2 → M3,2
by T(X) = A ◦ X (the Schur-Hadamard product of
A and X). What is the range of T? What is the
kernel of T? Therefore what is rank(T)? Explain
your answers.
