Piecewise-linear分段线性、Piecewise-polynomial分段多项式、Polynomial多项式 需要注意的是,这三种方式的自变量必须是温度,即材料物性依赖于温度变化。 2. Piecewise-linear:分段线性 所谓分段线性,就是分段的一次函数,可用坐标点来确定一次函数解析式。比如给两个点可以确定一段一次函数,三个点可以确定两段一次函数,依次类...

The operational matrix of piecewise linear polynomial functions is derived. Then the problems of analysis and parameter identification are studied on this piecewise linear polynomial basis. The algorithms proposed are analogous to those derived for the orthogonal functions. The piecewise polynomial basis ha...

Many engineering models, while highly nonlinear globally, are approximately piecewise linear. The linear Shepard algorithm, which is a moving window weighted least squares method based on linear functions, usually creates reasonable approximations. However, when used to produce approximations for data obtai...
摘要: A new approximation method with piecewise linear polynomial functions based on the application of the operational matrix for integration is presented. It is shown that this approximation is more satisfactory than the block-pulse approximation. Two illustrative examples are given....
