Matrix

 

 The knowledge of matrices is necessary for various branches of mathematics. Matrices

are one of the most powerful tools in mathematics and it simplifies our work to a great extent when compared with other straight forward methods. Matrix notation and operations are used in electronic spreadsheet programs for personal computers, which in turn is used in different areas of business and science like budgeting, sales projection, cost estimation, analyzing the results of an experiment, etc.
