LinExpr()
LinExpr ( arg1=0.0, arg2=None )
Linear expression constructor. Note that you should generally use overloaded operators instead of the explicit constructor to build linear expression objects.
This constructor takes multiple forms. You can initialize a
linear expression using a constant (LinExpr(2.0)),
a variable (LinExpr(x)), an expression (LinExpr(2*x)),
a pair of lists containing coefficients and variables, respectively
(LinExpr([1.0, 2.0], [x, y])), or a list of coefficient-variable
tuples (LinExpr([(1.0, x), (2.0, y), (1.0, z)])).
Return value:
A linear expression object.
Example usage:
expr = LinExpr(2.0) expr = LinExpr(2*x) expr = LinExpr([1.0, 2.0], [x, y]) expr = LinExpr([(1.0, x), (2.0, y), (1.0, z)])
