fractional_factorial_size Subroutine

public subroutine fractional_factorial_size(nfactors, fraction, m, n)

Computes the size of a fractional factorial design.

A 2^(k-p) fractional factorial design has 2^(k-p) runs. For example: 2^(3-1) has 4 runs for 3 factors (1/2 fraction).

Arguments

Type	Intent	Optional	Attributes		Name
integer(kind=int32),	intent(in)			::	nfactors	Number of factors (k).
integer(kind=int32),	intent(in)			::	fraction	Fraction level (p): 1 for 1/2, 2 for 1/4, 3 for 1/8, etc.
integer(kind=int32),	intent(out)			::	m	Number of runs (rows).
integer(kind=int32),	intent(out)			::	n	Number of factors (columns), same as nfactors.
