Decreased( tbl, reducibles, mat )
Decreased( tbl, reducibles, mat, choice )
tries to solve the output of OrthogonalEmbeddings
OrthogonalEmbeddings
or Extract Extract
in order to find
irreducible characters. tbl must be a character table, reducibles
the list of characters used for the call of OrtgogonalEmbeddings
or
Extract
, mat one solution, and in the case of a solution returned by
Extract
, choice
must be the corresponding choice
component.
Decreased
returns a record with components
irreducibles
:
remainders
:
matrix
:remainders
component, which could not be solved.
