A Span of Vectors Calculator is a simple online tool that computes the set of all linear combinations of two vectors or more.
在数学中span是扩张空间的意思。就是若干个向量通过线性组合得到的一个向量空间（满足向量空间的所有要求）。Span列向量是矩阵中所有的列span成的空间。S为一向量空间V（附于体F）的子集合。所有S的线性组合构成的集合，称为S所张成的空间，记作span(S)。
令N 代表股票数量, J 代表公司特征(firm characteristics)数量,令 N×J 维矩阵 XXt 表示t 时刻的所有股票的全部特征(其中第一列是 a vector of ones)。此外,令 zzt+1 代表N 个股票 t+1 时刻的超额收益率向量。定义如下条件预期收益率和条件协方差矩阵: μμt=E[zzt+1|XXt] ΣΣt=var(zzt+1|XXt)...
Pharmacological attenuation of mTOR presents a promising route for delay of age-related disease. Here we show that treatment of Drosophila with the mTOR inhibitor rapamycin extends lifespan in females, but not in males. Female-specific, age-related gut p

Let $L^{n}(3)$ be the $(2n+1)$-dimensional standard lens space mod 3 and let $nu$ denote the normal bundle associated to an immersion of $L^{n}(3)$ in the Euclidean $(4n+3)$-space. In this paper we obtain a theorem on stable unextendibility of $R$-vector bundles over $...
