Analytical Mathematics: Matrices
Matrices
Matrices are a grouping of numbers or symbols that represent numbers in a semi-rectangle that are placed into order through one or a series of vertical lines known as columns and one or a series of horizontal lines known as rows. Matrices come in many sizes, they can be as few as one number and could go all the way to infinity. Not just one number or letter can be placed in a space a whole equation with numbers and variables can be placed in a single space. A matrix by itself though is useless, but when a number or equation is placed outside of it can now be multiplied. If a matrix is placed next to another matrix then the possibilities and problems that can be solved are almost endless of what can be accomplished. A matrix can be added, subtracted, multiplied, divided, and can have the inverse taken out of it. When a matrix is placed parallel to another matrix separated by a plus symbol, one very important thing must be taken into consideration. Which is do the matrices being added together have the same number of rows and columns, for example, matrix one is a three by three which means it has three rows and three columns and matrix two is also a three by three. The first step is to add up the first row in matrix one with the first column in row two and then again for the second row and column. After those steps are followed the addition of the matrix should be complete. In subtraction of matrices the same steps should be

These data have been extensively analyzed with respect to their network topology, which has revealed a number of complex network properties, including small-world and scale-free characteristics and high modularity and clustering. However, these studies have been conducted almost exclusively on binarized

However, the classical solution frequently no exists and for those problems where is possible the use of these analytical methods, many simplifications are done [2]. Consequently, several numerical methods have been developed to efficiently solve EPDE such as the finite element method (FEM), finite difference and others. The FEM have several advantages over other
