Warning and Error Message
Error Condition Additional Information
Relation input not supported Relation input not supported
Note: The following relation inputs are
supported:
• Relations using ≤, <, =, >, or ≥.
• Polynomial relations in x and y
• Relations equivalent to y=f(x) or x=g(y) or
corresponding inequalities
• The above relations on domains
restricted by rectangles
Domain Restrictions not
supported for certain classes of
relations equivalent to y=f(x) or
x=g(y) or corresponding
inequalities.
• Relations equivalent to y=f(x) and
corresponding inequalities can only have
constraints on x
• For example: y=√(x) and 0≤x≤1 will work
but y=√(x) and 0≤y≤1 will not
• Relations equivalent to x=g(y) and
corresponding inequalities can only have
constraints on y
• For example: x=sin(y)|−1≤y≤1 will work
but x=sin(y)|−1≤x≤1 will not
