**NAME**

cws.x, cws-<num>d.x - create weight systems and combined weight systems.

**SYNOPSIS**

cws.x-<options>

**DESCRIPTION**

The cws-<num>d.x variant programs, where <num> is one of 4, 5, 6 and 11 work in different dimensions ; cws.x defaults to dimension 6. Beware: the first option must be -w, -c, -i, -d or -h.Options-hprint this information-fuse as filter; otherwise parameters denote I/O files-w# [L H] make IP weight systems for #-dimensional polytopes. For #>4 the lowest and highest degrees L<=H are required.-r/-t make reflexive/transversal weight systems (optional).-c# make combined weight systems for #-dimensional polytopes. For #<=4 all relevant combinations are made by default, otherwise the following option is required:-n[#] followed by the names wf_1 ... wf_# of weight files currently #=2,3 are implemented. [-t] followed by # numbers n_i specifies the CWS-type, i.e. the numbers n_i of weights to be selected from wf_i. Currently all cases with n_i<=2 are implemented.-icompute the polytope data M:p v [F:f] N:p [v] for all IP CWS, where p and v denote the numbers of lattice points and vertices of a dual pair of IP polytopes; an entry F:f and no v for N indicates a non-reflexive `dual pair'.-d# compute basic IP weight systems for #-dimensional reflexive Gorenstein cones;-r# specifies the index as #/2.-2adjoin a weight of 1/2 to the input weight system.-Nmake CWS for PPL in N lattice.
