numpoly.ndpoly.isconstant

ndpoly.isconstant() → bool

Check if a polynomial is constant or not.

Return:

True if all elements in array are constant.

Example:

>>> q0 = numpoly.variable()
>>> q0.isconstant()
False
>>> numpoly.polynomial([1, 2]).isconstant()
True
>>> numpoly.polynomial([1, q0]).isconstant()
False
