factor

Syntax

f = factor(n)

Description

example

f = factor(n) returns a row vector containing the prime factors of n. Vector f is of the same data type as n.

Examples

collapse all

f = factor(200)
f = 

     2     2     2     5     5

Multiply the elements of f to reproduce the input value.

prod(f)
ans = 200
n = uint16(138);
f = factor(n)
f = 1×3 uint16 row vector

    2    3   23

Multiply the elements of f to reproduce n.

prod(f)
ans = 138

Input Arguments

collapse all

Input value, specified as a real, nonnegative integer scalar.

Example: 10

Example: int16(64)

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64
