实数运算 meaning in Chinese
real arithmetic
Examples
- Perhaps , but at some point , i must deal with the fact that real number arithmetic is not exact on digital computers
也许，但在某种程度上，我必须处理实数运算在计算机上是不精确的事实。 - Due to the real operations and the fast dht algorithms utilized for the fast computation of the rdgt , the parallel lattice structures of the rdgt can more easily be implemented than in the cdgt case
这种方法由于仅涉及实数运算，并可借助于快速离散hartley变换算法，从而使rdgt的并行格型结构实现比cdgt要简单得多。 - It is shown that , due to the real operations , the computation of the bi - orthogonal analysis window , the transforms coefficients , and the reconstruction of the original signal in rdgt case , can be significantly reduced as compared with the computation of those in the cdgt case . and the similarity between the rdgt and the discrete hartley transform ( dht ) allows the rdgt to utilize the fast dht algorithms for fast computation . meanwhile , the rdgt bears a simple relationship with the cdgt such that the cdgt coefficients can be directly computed from the rdgt coefficients
主要内容有：研究了一维和二维实值离散gabor变换( rdgt )方法，这种方法由于仅涉及实数运算，并可利用快速离散hartley变换算法加速变换，因而在计算双正交分析窗、变换系数以及信号重建方面都比复值离散gabor变换( cdgt )简单易于实现，并且rdgt系数与cdgt系数的实部和虚部有着非常简单的关系，因此前者的计算完全可以替代后者的计算，从而达到明显减小gabor变换计算量的目的。
