List objects are very general structures of Mathematica. Questions about how to create, add/remove elements, rearrange, nest, order, combine and display lists, sets, tables, arrays, vectors, matrices or tensors of any rank/dimension all belong here. Questions about more specific array structures like packed arrays or SparseArray objects should also use this tag.

Questions dealing with matrices or matrix algebra could also use the tag .
