Since R2021b. 2019 수능 국어 답지 Sep 5, 2008 · A vector space over the field R is often called a real vector space, and one over C is a complex vector space. In Mathematica, you could construct such matrices, but usually you can deal with just vectors. The study of matrices as linear functions is central to the field of linear algebra. Thus, all vectors are inherently column vectors. If A is a multidimensional array, then max (A) operates along the first dimension of A whose size is greater than 1, treating the elements as vectors. This corresponds to the maximal number of linearly independent columns of , in turn, is identical to the dimension of the vector space spanned by its rows.
