t_SCHUR_SYMCHAR

synopsis: INT t_SCHUR_SYMCHAR(OP sp, res)

description:

the input is a SCHUR object sp, this is a sum of partitions with coefficent, this is interpreted as a decomposition of a charcter into irreducible ones. This sum of irreducible characters is computed, and will be the output, the SYMCHAR object res. If the partitions are of different weight, you will get an error. If the input is not a SCHUR object, the routine copies sp to res. More or less this routines computes the Frobenius isometry.
