Question

Who is the father of matrices?

Answer 1

In mathematics, a matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns. For example, the dimension of the matrix below

1 & 2 & 4 \\\ 3 & 6 & -20 \\\ -5 & 15 & 3 \\\ \end{matrix} \right]$$ is 3 $$\times $$3 it is read as ‘three by three’, because there are three rows and three columns. The rows are counted as the number of lines of numbers present horizontally, and the columns are counted as the number of lines of numbers present vertically. **Complete step by step solution:** Arthur Cayley is the father of matrices. He was a great mathematician. Arthur Cayley was born on 16th August 1821. It was in 1858 that Arthur Cayley published the theoretical definition of the matrix in his Memoir on the Theory of Matrices. After this, matrices have been established as one of the branches of mathematics. Matrices can be used for many purposes in mathematics. One of them is solving linear equations. To solve the given simultaneous linear equations in unknowns, we have to use the elimination method and the substitution method. **Note:** Matrices are used for many purposes in real life. Some of them are listed below: The matrices are used for plotting graphs, different function, statistics and also to do scientific studies and research in almost different fields. Matrices are best methods of representation methods to plot the data we get from different surveys. The data can be of many types, some of the examples are population of people, infant mortality rate, etc.
