TEST PROCEDURE
- Propagate the
IN1 value by double-clicking
on a table cell, then striking the Enter key:
- The
IN1 value will
propagate to OUT1, whose table size will adjust to
the new value.
- The
QO=FALSE and STATUS=13(ARRAY_SIZE_ERROR)
outputs for ADD, SUB, MUL indicate the as-yet
unknown size of the IN2 matrix.
- The inversion operation has failed
with
STATUS=4 (DIVISION_BY_0), indicating that IN1
is singular; however, note that the product IN1*INV
does give a 2×2 identity submatrix for that portion of
the matrix for which the inversion procedure succeeded.
- Propagate the IN2 value by double-clicking on a table
cell, then striking the Enter key.
- The
ADD, SUB, MUL operations will complete
successfully, but IN1 is still singular.
- Double-click at IN122, type in
1.0
and Enter.
- The
ADD, SUB and MUL results
will be updated.
- the
INV operation will complete
successfully, and IN1*INV will show a 3×3
identity matrix as expected.
