One of the oldest concepts in mathematics is conjugates and Determinants.In the 2nd and 4th century BC there were traces.In the 17th Century the concepts were well developed.When mathematicians tried to solve a problem related to multiple simultaneous linear equations they needed matrices and determinants.Some of the clay tablets made with the matrices from the Babylonians era are still preserved.

This can be applied to the normal life.The matrices are used to solve complex problems with a computer.Predictive model developments using matrices are included in the analytics problems.The word matrix was created by a lawyer in association with a mathematician in the 17th century.The concept of matrix was used in mathematics in a powerful way.

In terms of organised 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 was made up of the quadratic form.This was done by Gauss in the 17th century.The concept of determinants was expanded by another renowned mathematician.The coefficients of linear equations can be written with matrices.

Data is represented in excel spread sheet as a matrices and it is used in almost all corporates and educational institutions.Many of the dashboards that are developed for management decision making and operational analysis are in a matrices format with rows and columns.A table with years in the columns and states in the rows can be used to depict the population of India over the past 10 years.A matrix is a rectangular array of elements distributed in two dimentionals.The rows and columns are usually covered with a square brackets to indicate that a matrix has been created.

If the matrices have A number of rows and B number of columns then the size of the matrices is determined by the multiplication of A * B.The size of the matrices is 50 if there is 10 rows and 5 columns.The matrices that have only one row are called row matrices.Column matrices are matrices that have only one column.The zero matrices are a type of matrices where the elements of the matrices are 0.

It is called a void matrix or null matrix.The square matrices have an equal number of row and column elements.The elements that fall in the diagonal line are represented by the principal diagonal.There are some names for the diagonal.It is also referred to as main diagonal or leading diagonal elements.

The unit matrix have values only in the diagonal and the rest of the elements are zero.The diagonal elements have a value of 1.The triangular matrix can be found in the square matrix.If all the elements in the bottom of the diagonal are zero it's called a triangular matrix.If all the 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 is called an equal matrices.Adding multiplication and subtracting can be done with algebric operations.There is only one way to division two matrices.There are certain things we need to be satisfied before we perform the operations.If we have a matrix with a constant then we need to add all the elements of the matrix with the same element.

We can add and subtract matrices if they have the same number of rows and columns.The addition of matrix A with matrix B shows A+B of each of the elements of the matrices.The A-B of each of the elements of the matrices are indicated by the subtraction of Matrix A with matrix B.We need to know if the number of rows and columns of one matrix is the same as the number of rows and columns in the other matrix.We need to say in the result that an addition or subtraction is not possible if not.
