`plus`

Function form of the addition operator +.

Category: Language Fundamentals > Data Types

Syntax

C = plus(A, B)

Adds A and B element by element. Same as A + B.

Description

plus(A, B) is exactly what the + operator calls. It is useful where a function handle is needed, as in arrayfun(@plus, a, b), and it is the name a class overloads to define addition for its own objects.

Implicit expansion applies: a column plus a row gives a matrix. Integer types saturate rather than wrap around.

Input arguments

A, B: Numeric, logical or char arrays, duration or datetime values, or objects that define plus. Sizes must be compatible.

Output arguments

C: The sum, with the size produced by implicit expansion.

Example

plus(1, 2)
plus([1 2], [10; 20])
plus(int8(100), int8(100))

Output

ans = 3
ans = 2×2

    11    12
    21    22
ans = int8
   127
