The README File
This set of Matlab scripts will calculate the irreducible characters and
the irreducible matrix representatives of a finite group.

IrrepMain.m is the main script which will read the input data and will
during execution call the functions inverse.m, genera.m, classes.m,
charac.m (modulus.m), repres.m, permu.m, degen.m, intsec.m, subsp.m,
eigvec.m and mgt.m.

Three input files shall be submitted for execution. The contents of
steer.dat will control the amount of output data. One file containing the
order of the group and one file containing the multiplication table of the
group shall be supplied.

Example input files are supplied; order_C3.dat, C3.dat for the group C3,
order_D4.dat, D4.dat for the group D4 and order_C4v_C4v.dat, C4v_C4v.dat
for the group C4vxC4v.

This program package is an extension of the QCPE 169 Fortran program.
This set of files will also handle irreducible representation matrices
with no non-degenerate eigenvalues of the matrix representatives. The
finite group C4vxC4v is an example of this problem.

These set of files is a stand alone program package. The Matlab scripts
are also used by SYMPRJ.m/SYMPW.m and SYMPRJS.m/SYMPWS.m as Matlab
functions.

Program-Irrep.doc(pdf).
