One of the oldest concepts in the history of mathematics is matrices and determiningants.It was in the 2nd and 4th century BC.The concepts were developed in the 17th centuryThe mathematicians needed matrices and determinants when they were trying to solve a problem.Some of the clay tablets created during the Babylonians era are still preserved.

This can apply in the normal life.In modern applications the matrices are used to solve problems using a computer.Predicting and model developments using matrices are included.The word matrix was invented by a lawyer and mathematician in the 17th century.Since the concept of matrix was invented it has a powerful application in mathematics.

In terms of organizing cars in a parking area coconut trees in a farm land and storage of boxes in a storage area we can see matrices.The basis for the term is the form of the quadrupole.This was created by Gauss in 17th century.The concept of indicators was expanded by another mathematician.The coefficients of the linear equations are written using matrices.

Most corporates and educational institutions use excel spread sheet to represent their data.Many of the dashboards developed for management decision making and operational analysis are in a matrices format with tables that are rows and columns.A table with years in the columns and states in the rows can be used to show the population of different states in India for the past 10 years.There are rows and columns distributed in a rectangular array of elements.The square brackets are usually put over the rows and columns to show that there is a matrix.

The size of the matrices is determined by how many rows and columns it has.If there are 10 rows and 5 columns in the matrices the size is 50.Row matrices are the matrices that have only one row.Column matrices are matrices that don't have any more than one column.The zero matrices are type of matrices where all elements are 0.

It's also known as void matrix or null matrix.The matrices have the same number of row elements and column elements.There are elements that fall in the diagonal line that are represented in a square matrix.Different names exist for the diagonal.It's also called diagonal main diagonal or leading diagonal elements.

The units have values only in the diagonal and the rest of the elements are zero.In the diagonal elements all the elements have the same value.A special type of matrix can be found in the square matrix.If all of the elements in the bottom of the diagonal are zero it is called the triangular matrix.If all elements of the matrices are equal we can say that the two matrices are equal.

If any of the elements are not the same or not in the same order it's called an equal matrices.Adding multiplication and subtracting are some of the algebric operations that can be done.There is only the division of two matrices that can be done.Before we can do the operations there are certain requirements to be satisfied.If we have a matrix with a constant then we need to add all the elements with the same element.

If both matrices have the same number of rows and columns we are able to add and subtract them.The A+B of the elements of the matrices is determined by the addition of matrix A and matrix B.The A-B of the elements of the matrices are indicated by the multiplication of Matrix A with matrix B.If the number of rows and columns in one matrix is the same as the number of rows and columns in another matrix we need to add or subtract that matrix.We need to say in the result that such an addition is not possible.
