Arithmetic functions include operators for simple operations like addition and multiplication, as well as functions for common calculations like summation, moving sums, modulo operations, and rounding.

Custom Binary Functions
- Array vs. Matrix Operations
Matrix operations follow the rules of linear algebra, and array operations execute element by element operations and support multidimensional arrays. The period character (
.) distinguishes the array operations from the matrix operations.
- Compatible Array Sizes for Basic Operations
Most binary operators and functions in MATLAB® support numeric arrays that have compatible sizes. Two inputs have compatible sizes if, for every dimension, the dimension sizes of the inputs are either the same or one of them is 1.
- Operator Precedence
Precedence rules determine the order in which MATLAB evaluates an expression.
- Floating-Point Numbers
MATLAB represents floating-point numbers in either double-precision or single-precision format. The default is double precision.
MATLAB supports 1-, 2-, 4-, and 8-byte storage for integer data. If you use the smallest integer type that accommodates your data, you can save memory and program execution time.
