replace part of a wedge product
expression involving wedgeproducts
expression of the form wedgeprod = expression
list or set of expressions like eqn
This routine is part of the liesymm package and is loaded via with(liesymm) .
The routine wsubs() is analogous to powsubs() but is for wedge products. One or more equations specify replacements that are to be made.
The replacements occur even if only a subset of the &^ arguments match.
If two or more substitutions are specified, they are completed in the order specified, even if they are given as a set. Simultaneous substitution (as in subs()) has not been implemented.
