"分段函数,就是对于自变量x的不同的取值范围,有着不同的解析式的函数。它是一个函数,而不是几个函数;分段函数的定义域是各段函数定义域的并集,值域也是各段函数值域的并集。" "In mathematics, a piecewise-defined function (also called a piecewise function or a hybrid functio... ...

Although the "pieces" in a piecewise definition need not be intervals, a function is not called "piecewise linear" or "piecewisecontinuous" or "piecewise differentiable" unless the pieces are intervals. WikiMatrix The topological,piecewise-linear, and smooth categories are all equivalent in three di...

2. We now describe the approach in [136] to study the local ergodicity. A continuous function Q:TM→ℝ is called an infinitesimal eventually strict Lyapunov function for f over a set U ⊂ M if: 1. for each x∈ U the function Qx = Q \ TxM is homogeneous of degree one, and ...

Based on a hybrid orthogonal function, a new linear, continuous and bounded operator, piecewise general orthogonal polynomials operator (PGOPO), is proposed. Its main properties and operational rules have been strictly constructed based on the theory of convergence in the mean square, and are ...
This paper presents a method for directly estimating slope values in a noisy piecewise linear function. By imposing a Markov structure on the sequence of slopes, piecewise linear fitting is posed as a maximum a posteriori estimation problem. A dynamic program efficiently solves this by traversing a...
