Hi, Michael. Thank you for your response. I need to create a 100 x 100
banded and dense matricies and then calculate the condition number for
each matricies. For the sparse matrix, I know that sprand (m, n ,
density) command. I am not sure how to create banded matrix with a big
dimension. A dense matrix means that a matrix with non-zero componts.
In that case, can I just use rand (10, 10) for any numbers? Any hint
