I guess the issue is that I'm not directly inserting the data into the
SerialDenseMatrix object's flat array, but using the () operator.  For
(i,j) the documentation describes i as being the row and j being the
column -- how the value is stored internally is opaque.  I see no
options to SerialDenseMatrix constructors that indicate a preference
for internal format.
