tol
are considered equal.ddmatrix
.bldim
is set inappropriately).For example, verify.solve()
will generate the A
matrix and "true solution" x
to the problem Ax=b
,
each as distributed objects. Next, the "right hand side" b
is generated by multiplying A
and x
together.
Finally, the numericaly solution x
is computed and compared
against the known true value at the specified numerical tolerance.
