Rank and Nullity This activity shall determine the rank and nullity of a matrix. Create a function that will be able to solve the following: a. accept the a rectangular array of elements. b. compute the rank c. compute for the nullity of the matrix d. identify the rowspace of A e. identify the column space of A. Refer to the discussion item at the MATLAB Discussion handout. [Rank, Nullity, Rowspace, Nullspace] = ranknullity(A)
