One of the oldest concepts in mathematics is matrices and determiningants.It hasThe concept was well developed in the 17th century.There was a need for matrices and determinants when the mathematicians tried to solve the problem.Some of the clay tablets with the matrices which are still preserved are from the Babylonians era.

This has applications in the normal life.The matrices are often used to solve complex problems using a computer.Predicting and prescriptive model developments are included in the analytic problems.The word matrix was created by a lawyer and a mathematician during the 17th century.The concept of matrix had a powerful application to the concepts of mathematics.

In relation to organised cars in a parking area coconut trees in a farm land and storage of boxes in a storage area we can see matrices in common practise.The basis for the term determinants is found in the form of the quadratic form.Gauss invented this in 17th century.The idea of determinants was expanded by a famous mathematician.We can use matrices to write the coefficients of linear equations.

In data is represented in excel spread sheet as a matrix and it is used in almost all corporates and educational institutions.Many of the dashboards developed for management decision making and operational analysis are also 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 in India over the past 10 years.The rows and columns of the matrix are distributed in two dimentionals.We usually put a square brackets over the rows and columns to show that everything is in a matrix.

The size of the matrices is determined by how many rows and columns they have.If there are 10 rows and 5 columns then the size of the matrices is 50.Row matrices are the matrices that only have one row.Column matrices are the matrices that have only one column.The zero matrices are a type of matrices where the elements are 0.

It's also known as a null matrix.The square matrices have the same number of rows and column elements.A square matrix has a principal diagonal which is represented by elements that fall in the diagonal line.There are a number of different names for the diagonal.It is also called main diagonal or leading diagonal elements.

The rest of the elements are all zero in unit matrix which has values only in the diagonal.All of the elements have the same value.A triangular matrix is a special type of square matrix.The triangular matrix is defined as the square matrix if all the elements in the bottom of the diagonal are zero.If all the elements in the matrices are equal then both are equal.

If any of the elements are not the same or not in the same order it is called a unequal matrix.Adding multiplication and subtracting are some of the operations we can do on matrixes.The division of two matrices is not doable.There are certain things that must be satisfied before we can perform the operations.If we have to multiple a matrix with a constant then we need to add the elements of the matrices together.

If both matrices have the same number of rows and columns then we can add and subtract them.The A+B of each of the elements of the matrices is shown by the addition of matrix A with matrix B.The A-B of each of the elements is indicated by the subtraction of Matrix A with matrix B.If the number of rows and columns of one matrix is the same as the number of rows and columns in the other matrix then we need to add or subtract them.We need to say in the result that an addition or subtraction is not possible.
