# What is the matrix theory in math?

Matrix theory is a branch of mathematics which is focused on study of matrices. Initially, it was a sub-branch of linear algebra, but soon it grew to cover subjects related to graph theory, algebra, combinatorics and statistics as well.

Similarly, it is asked, how do matrices work?

In order to multiply matrices, Step 1: Make sure that the the number of columns in the 1st one equals the number of rows in the 2nd one. (The pre-requisite to be able to multiply) Step 2: Multiply the elements of each row of the first matrix by the elements of each column in the second matrix.

Where do we use Matrix in real life?

In geology, matrices are used for making seismic surveys. They are used for plotting graphs, statistics and also to do scientific studies and research in almost different fields. Matrices are also used in representing the real world data's like the population of people, infant mortality rate, etc.

What is the Matrix diagram?

A Matrix Diagram (MD) is a tool that allows a team to identify the presence and strengths of relationships between two or more lists of items. It provides a compact way of representing many-to-many relationships of varying strengths. An example matrix diagram is shown in figure 1.
