Absolute value functions have a parent function, f(x) = a|x| Example. Graph f(x) = -3|x| Parent function? What is a? Piecewise Functions Piecewise = function defined in terms of two or more formulas – Come to a “stop-sign” – Stop sign then directs us which particular function...
8.4 Laplace transforms of step and periodic functions 8.4.1 Piecewise defined functions: the unit step function An important function in modeling many physical situations is the unit step function, U. Definition 8.6 Unit step function Consider the unit step function, U(t−a)=Ua(t), where a...
A step function, also known as a staircase function, is a real-number function that can be written as a finite linear combination of interval indicator functions. Informally, a step function is a piecewise constant function with a finite number of pieces. On given intervals, a step function ...

The Piecewise function also permits smoothing between intervals. If you are setting up other types of user-defined loads, make sure to add some kind of smoothing to them as well. For more information see the COMSOL Multiphysics Reference Manual > Global and Local Definitions > Functions > ...
The Lagrangian dual (LD) problem, aimed at finding the best lower bound, is defined as:(3.12)zLD=maxλ≥0z(λ). The Lagrangian dual is a maximization problem where the objective function is nonsmooth, in particular it is concave and piecewise affine. We have applied to it the method...

2.1.2 Step functions We shall define the Heaviside unit step function, u, as that function which is equal to 1 for every positive value of t and equal to 0 for every negative value of t. This function could equally well have been defined in terms of a specific formula; for example ...
