Remark: You may only use rref , or commands that are covered inour MATLAB guides, and no other special MATLAB functions for thisproblem.
(a) (3 points) Find a basis for Col(A) and determine itsdimension.
(b) (5 points) Find a basis for Nul(A) and determine itsdimension.
(c) (3 points) Find a basis for Row(A) and determine itsdimension.
(d) (5 points) Find a basis for the left nullspace of A anddetermine its dimension.
(e) (2 points) Find a basis for Col(B) and determine itsdimension.
(f) (6 points) Determine whether Col(A) = Col(B), i.e. determinewhether the two given subspaces of R 5 are the same or not. If not,find a vector v
that belongs in one of the subspaces and not the other.
(g) (6 points) Determine whether Nul(A) = Nul(B). If not, find avector v that belongs in one of the subspaces and not theother.
