parserAssignment
only allows the expression in the form "x = ..." or "y = ...", so it would not accept x - y = 1
as equivalent to y = x - 1
.On the other hand,
x - y = 1
is better handled through parserImplicitPlane.pl
than parserImplicitEquation.pl
. It is best to avoid ImplicitEquation
whenever possible. Davide
