Hello!
I wrote a program that works fine in version 4, using InequalitySolve
to solve systems of linear inequalities,
and wanted to adapt it for use of a student who
has only access to version 3.
I ran into unexpected problems. Take this example:
($Version="Solaris 3.0 (August 21, 1997)")
Needs["Algebra`InequalitySolve`"]
InequalitySolve[(y > 0) && (y < 1), {x, y}]
This command gives back the input and produces 3 messages,
one of which is funny:
InequalitySolve::"nlin": "\!\(\(y > 0\) && \(y < 1\)\) is not a formula \
constructed with linear equations and inequalities in \!\({x, y}\)."
Is this a bug? Can I forget about using InequalitySolve v.3?
