===Purpose===

Output a fractional factorial design matrix.

===Synopsis===

:desgn = ffacdes1(k,p)

===Description===

FFACDES1 outputs a 2<sup>(k-p)</sup> fractional factorial design of experiments. The design is constructed such that the highest order interaction term is confounded. This is one way to select a fractional factorial. Input k is the total number of factors in the design and p is the number of confounded factors {default: p = 1}. Note that it is required that p < k. Output desgn is the experimental design matrix.
