A.11 Operators
MATLAB has operators to perform calculations involving arithmetic, logical, relational, and conditional operations.
A.11.1 Arithmetic Operators
There are two types of arithmetic operations in MATLAB: matrix arithmetic operations, which are governed by
the rules of linear algebra, and arithmetic operations with vectors, which are performed element to element. The
operators involved are presented in the following table.
