Matrices - Defination, Notes
What is Matrice?
Matrices are rectangular grids of numbers or symbols used to organize and manipulate data. They find applications in mathematics, physics, computer science, and engineering. Matrices can be added, subtracted, and multiplied, and they allow for operations like transposition. They are crucial for solving systems of linear equations, performing transformations, and analyzing data in statistics. Matrices play a fundamental role in linear algebra, calculus, and differential equations. They provide a versatile tool for organizing data, making calculations, and solving complex problems in various fields.
