Arithmetic Operators
These binary operators perform arithmetic on their operands. The two operands for an element-wise arithmetic operator must be the same size. Operators that are not element-wise are not so uniform; they may have other operator-specific restrictions on operand size.

Because the MATLAB syntax differs from the C++ syntax, several MATLAB operators are available in C++ as functions rather than as operators.
