Create a piecewise function handle. foo = PIECEWISE (f1,border,f2,border,f3,...) returns a function handle to a piecewise combination of provided functions (or constants), transitioning from one ...

The optimal solution of linear programming problem (17) is the best piecewise linearization of the function on.We let (See Figure 5).In this example, we have while for Splines Piecewise Approximation ...

OmniGraphSketcher is an iPad app that makes it easy to create gorgeous and precise graphs with lines, curves, shaded regions, and more. Instead of using specific equations, like a graphing calculator, ...

The purpose of this paper is to propose a generalization of piecewise linear Lyapunov functions (PLLFs). In original PLLF candidates, functions are parameterized by hyperplanes, which intersect the ...

Nonlinear approximation is widely used in signal processing. Real-life signals can be modeled as functions of bounded variation. Thus the variable knot of approximating function could be self- ...

Piecewise smooth (PWS) images (e.g., depth maps or animation images) contain unique signal characteristics such as sharp object boundaries and slowly varying interior surfaces. Leveraging on recent ...

We consider piecewise H¹ functions and vector fields associated with a class of meshes generated by independent refinements and show that they can be effectively analyzed in terms of the number of ...
