bbdesign
Box-Behnken design
Syntax
dBB = bbdesign(n)
[dBB,blocks] = bbdesign(n)
[...] = bbdesign(n,param
,val
)
Description
dBB = bbdesign(n)
generates
a Box-Behnken design for n
factors. n
must
be an integer 3
or larger. The output matrix dBB
is m-by-n
,
where m is the number of runs in the design. Each
row represents one run, with settings for all factors represented
in the columns. Factor values are normalized so that the cube points
take values between -1
and 1
.
[dBB,blocks] = bbdesign(n)
requests
a blocked design. The output blocks
is an m-by-1
vector of block numbers for each run. Blocks indicate runs that are
to be measured under similar conditions to minimize the effect of
inter-block differences on the parameter estimates.
[...] = bbdesign(n,
specifies
one or more optional parameter/value pairs for the design. The following
table lists valid parameter/value pairs.param

Parameter | Description | Values |
---|---|---|
'center' | Number of center points. | Integer. The default depends on |
'blocksize' | Maximum number of points per block. | Integer. The default is |
