History

The correct input should have been the transpose of the matrix.

The problem was an incorrectly sized vector; the bug was "hidden" by a poor choice of variable name (was row, now changed to col_j).

Two quick tests passed. Maybe I'd better add a couple of tests to the suite?

works ok for me.

There seems to be documentation now.
I have just added a new test test-MatrixOps1.C which tests the input given in the description.

Closing.
