covmat
Values of cluster covariance matrix are stored
in covmat
table.
Attributes conf_id
, ccluster
identifies covariance matrix.
Value position in matrix is specified by rind
and cind
fields.
conf_id
is id of configuration which cluster belongs to.
ccluster
is id of cluster which matrix belongs to.
rind
is row number in covariance matrix
cind
is column number covariance matrix
val
is value itself (variance or covariance).
Values rind
and cind
have to respect dim
and band
specified in table clusters
.
If value in covariance matrix is not specified (record is missing),
it is considered to be zero.
Example (table contents):
conf_id|ccluster|rind|cind|val -------------------------------- 1 |1 |1 |1 |400.0 1 |1 |2 |2 |400.0 1 |1 |3 |3 |400.0 1 |4 |1 |1 |400.0 1 |4 |2 |2 |400.0 1 |4 |3 |3 |400.0 1 |4 |4 |4 |400.0 |
