piecewise constant function

Moreover, the level set function can be flexibly initialized with a piecewise constant function rather than a signed distance function in practice.

同时该模型能够用一般的分段常数函数来定义初始水平集函数，即水平集函数不必初始化为符号距离函数。

Some simple and useful real-time processing approachs are discussed, such as generating test signals, checking out wrong information, recursive computing of correlative functions, approximately getting piecewise constant function, etc.

文中对一些简单实用的实时处理手段，如施加试验信号、剔除错误信息、递推相关运算以及近似地获取分段常值函数等，作了探讨。

The weak entropy solution of the problem is a piecewise constant function with finitely many shocks, in which the interaction is overtaking of shocks and colliding of shocks with the boundary.

无粘问题的弱熵解是含有有限个激波的分片常数函数，且含有激波的相互追赶及激波与边界相撞两种相互作用。
