Prime factors
Syntax
Description
Examples
Prime Factors of Double Integer Value
f = factor(200)
f = 1×5
2 2 2 5 5
Multiply the elements of f
to reproduce the input value.
prod(f)
ans = 200
Prime Factors of Unsigned Integer Value
n = uint16(138); f = factor(n)
f = 1x3 uint16 row vector
2 3 23
Multiply the elements of f
to reproduce n
.
prod(f)
ans = 138
