In this context a graph is hardly more than a visual or computational aid . 在這方面圖僅僅是直觀的和計算的一種工具。
This is a crude way to describe what is actually a somewhat more delicate computational problem . 對于本來是更為細致的計算問題,這是一個粗略的描述方法。
Fermat's principle is not so much a computational device as it is a concise way of thinking about the propagation of light . 費馬原理更多的是對光的傳播的一種簡明看法,而不是一種計算工具。
The property of symmetry can also be used to save a part of the computational effort required for matrix inversion or for a solution of equations . 對稱的特性也可用來節省矩陣求逆中或求解方程中所需要的一部分計算量。
