Closed Linear Span
In functional analysis, a closed linear span of a set of vectors is the minimal closed set which contains the linear span of that set. Suppose that X is a normed vector space and let E be any non-empty subset of X. The closed linear span of E, denoted by or, is the intersection of all the closed linear subspaces of X which contain E.
One mathematical formulation of this is
