scidoe_sortdesign

Sort the experiments of a design of experiments

Calling Sequence

D = scidoe_sortdesign(D)

Parameters

D :

a m-by-nbvar matrix of doubles, the design of experiments.

Description

Sorts the rows of a DOE, so that we gather the rows which are common, ignoring the signs of the entries.

In a DOE which has {0,-1,+1} entries, this gathers the blocks which have +-1 entries. This makes the factorial blocks of the design more obvious.

Examples

// A DOE with no obvious structure.
E = [
-1 1 0
-1 -1 0
0 0 0
1 -1 0
0 -1 1
-1 0 -1
0 1 1
-1 0 1
1 0 1
0 -1 -1
1 0 -1
0 1 -1
1 1 0
]
D = scidoe_sortdesign(E)
