许多控制问题都可以用线性分式变换（LFT）结构来表示。

Many control problems can be formulated in a linear fractional transformation (LFT) framework.

在高等代数的教学教研中，经常要涉及到有关分式恒等问题。

During the teaching and research of higher mathematics, we often touch upon the problems about fraction identically equal.

本文提出一个直接处理一般形式线性分式规划的算法而不需要把问题的约束条件转化为标准形式。

In this paper, the authors present an algorithm to handle linear fractional programming in the general form directly, which need not transform the constraints of the problem into the standard form.
