Question

The space located for the matrix generated from the spones command is _______

(a) Same as a sparse matrix

(b) Same as the original matrix

(c) Same as an identity matrix

(d) Double that of the sparse matrix

This question was posed to me by my college director while I was bunking the class.

My question is from Sparse Matrices in chapter Beyond the Basics of MATLAB

Answer 1

Correct answer is (a) Same as a sparse matrix

To elaborate: The spones command also creates a sparse matrix. Hence, the newly generated matrix will have the same size as that of a sparse matrix.
