• If you use /· or set the Auto or
Approximate mode to Approximate,
computations are done using floating-
point arithmetic.
• If Tol is omitted or not used, the default
tolerance is calculated as:
5E−14 •max(dim(Matrix1)) •rowNorm
(Matrix1)
Avoid undefined elements in Matrix1. They
can lead to unexpected results.
For example, if a is undefined in the
following expression, a warning message
appears and the result is shown as:
The warning appears because the
generalized element 1/a would not be valid
for a=0.
You can avoid this by storing a value to a
beforehand or by using the constraint (“|”)
operator to substitute a value, as shown in
the following example.
Note: See also rref(), page 132.
