查询词典 ellipsoids

Yellow ellipsoids are mail programs.

黄色椭圆是邮件程序。

The square root non-optimal algorithm can keep the shape-defining matrixes of the ellipsoids positive definite, so it is also numerically stable.

平方根非最优椭球集员滤波算法能使椭球形状矩阵保持正定性，因而它也具有较好的数值稳定性。

To gain larger RA, the developed method estimated RA of the cases using the volume of n full-dimensional ellipsoids as the criteria for stability of the closed-loop systems with different control laws.

为获得更大的吸引域，以n维椭球体体积为指标，对多组控制律进行评估和筛选。

On the other hand, a square root non-optimal set membership state estimation algorithm by ellipsoids is given, and the parallel computation of state estimation using systolic arrays is schemed.

另一方面，提出了一种平方根非最优椭球集员滤波算法，并给出了实现滤波计算的心动阵列结构。

Traditionally ellipsoids and hyperboloids are modeled as implicit surfaces or through the use of rational surface schemes. The existing methods for generating spheres or quadrics have shortcoming such as the rational parameterizations for these surfaces are non-uniform, the resulting scheme cannot represent these surfaces in their natural acr-length parameterization and the implementation of the scheme is complex.

长久以来，Subdivision方法对一些看似简单却又在计算机图形学中有着重要作用的曲线曲面的造型非常困难，即使是对简单的圆和球的生成也很困难，已有的一些生成球或二次曲面的Subdivision方法一般都有太复杂、不能自然弧长参数化或者计算量太大等缺点。
