In this lesson, we’ll cover matrices and data frames. Both represent ‘rectangular’ data types, meaning that they are used to store tabular data, with rows and columns. The main difference, as you’ll ...

Abstract: In this paper we present a programming language for writing programs for matrices operations, such as addition, subtraction, multiplication, determinant, inverse and cofactors and so on.

Convexity and generalized convexity play important roles in optimization theory. With the development of programming problem, there has been a growing interest in the higher-order dual problem and a ...

Sufficient conditions are given for a real matrix to be similar to a positive matrix. This result is used to construct a similarity transformation which, when applied to a particular upper triangular ...
