TheL¹ normis simply the sum of all the elements of the vector.It is used in machine learning when the system requires much more precision.To differentiate clearly between a zero and a non zero element. The L¹ norm is also known asManhattan norm. There is alsomax norm,which is th...

So for 10x8 you should really simply use a dense MatrixXf. Nonetheless, to fill a sparse matrix the recommended way is to fill an intermediate std::vector of Triplet like this: typedef Eigen::Triplet<double> T; std::vector<T> tripletList; tripletList.reserve(9); tripletList.push_back(...
In fact, there is a $K$-algebra with two elements $a,b$ such that $ab=1$, but $ba \neq 1$. Consider the left shift $a : K^{\mathbb{N}} \to K^{\mathbb{N}}$, $a(x_0,x_1,\dotsc) := (x_1,x_2,\dotsc)$ and the right shift $b(x_0,x_1,\dotsc) := (0,...

Linear algebra is another fundamental tool of mathematical economics, under several respects. Within this chapter we will show how Excel can deal with the basic linear algebra calculus via the built-in matrix functions. Then, also some key theorems of linear algebra will be explained and applied....

In linear algebra the term "linear operator" most commonly refers to linear maps (i.e., functions preserving vector addition and scalar multiplication) that have the added peculiarity of mapping a vector space into itself (i.e., ). The term may be used with a different meaning in other ...
