Matrices in R ProgrammingA matrix is a table of numbers. In math text, it is conventional to denote matrices with bold letters. For example, consider a matrix D of the prices of the securities on first three days of the week. 1D = 2 64 31 3 65 28 4 66 35 5 This matrix is {3...
In R, one requirement for matrices is that every data element stored inside it be of the same type (all character, all numeric, and so on). This allows you to perform arithmetic operations with matrices, if, for example, you have two that are both numeric. Let's use matrix() to ...

Matlab is an interactive environment and programming lan- guage for numeric scienti c computation 18]. One of its distinguishing features is the use of matrices as the only data type. In Matlab, a matrix is a rectangular array of real or complex numbers. All quantities, even loop variables ...

It is shown that if a feasible solution to a binary mathematical programming problem is represented as an N 脳 N matrix consisting of zeroes and ones, where there exists a single one in each row, then this matrix is periodic. From this result, it is proved that the eigenvalues of the ...

We extend Cho's cyclic group action to the triangulation in such a way that it corresponds to rotating centrally symmetric triangulations of a regular $(2n+2)$-gon. Finally, we present a bijection between the faces of the Simion's type $B$ associahedron and Delannoy paths. 阅读PDF 1 被...
However, the difference in performance between the Curveball algorithm and swap methods is not surprising. Let us imagine a matrix of R rows and C columns having only one checkerboard. A matrix of this kind admits only one alternative configuration. The probability to find this sole configuration...
The vector is a very important tool in R programming. Through vectors, we create matrix and data frames. Vectors can have numeric, character and logical values. The function c() is used to create vectors in R programming. For example, lets create a numeric vector: # numeric x <- c(1,...
