The matrix is a set of quantities

The matrix is a set of quantities (variables and constants) that can be referenced through the index, which stated its position in the general representation used, ie a table Rectangle. The matrix is a way of visualizing the variable which is a collection of numbers or other variables, such as vectors. With matrix representation, the calculation can be done with more structured. Utilization for example in explaining the linear equations, coordinate transformation, and others. Matrix as well as ordinary variables can be manipulated, such as multiply, add up, deductible and decomposed.



Matrix addition and subtraction

Matrix addition and subtraction can be performed by operating the matrix components at the same location, or denoted by

or in a decorative representation
