picture F
picture m
picture M
The sources and targets of the differentials in F = burkeResolution(M,n), where M is an R = S/Imodule, are direct sums whose summands are labeled, each by a List of ZZ corresponding to a tensor product of components of the Sfree resolutions of R and M.
The maps in the AInfinity structures are similarly labeled (each one has a source that has just one summand.)
When applied to such a map, picture prints it as a table, with columns labeled with the symbols associated to the source and rows labeled with the symbols associated to the target. When applied to a complex, the output is a "netList" display of the pictures of each of the maps.




The possible symbols in the table produced by picture are:
. if the corresponding matrix is zero * if the corresponding matrix is nonzero u if the entries of the corresponding matrix contain a unit.
The object picture is a method function.
