`./`

Element-wise right division operator.

Category: Language Fundamentals > Operators and Elementary Operations

Syntax

C = A ./ B

Divides each element of A by the matching element of B. Same as rdivide(A, B).

Description

Floating-point division by zero does not raise an error: 1./0 is Inf, -1./0 is -Inf and 0./0 is NaN. Sizes are expanded implicitly, so x ./ sum(x) normalizes a vector and A ./ max(A) scales each column of a matrix.

For integer types the quotient is rounded to the nearest integer and saturates; dividing by zero gives the largest value, or 0 for 0./0.

Input arguments

A: Numerator: numeric or logical array.
B: Denominator, with a size compatible with A.

Output arguments

C: Array of quotients.

Example

[2 4 6] ./ [1 2 3]
[1 0 -1] ./ 0
x = [1 2 3 4];
x ./ sum(x)
int32(7) ./ int32(2)

Output

ans = 1×3

     2     2     2
ans = 1×3

   Inf   NaN  -Inf
ans = 1×4

    0.1000    0.2000    0.3000    0.4000
ans = int32
