ShortestPathFunction[type, data] represents a function that gives the shortest path from a source vertex s to target vertex t in a graph.

Short[expr] prints as a short form of expr, less than about one line long. Short[expr, n] prints as a form of expr about n lines long.

Show[graphics, options] shows graphics with the specified options added. Show[g_1, g_2, ...] shows several graphics combined.

StruveL[n, z] gives the modified Struve function L n (z).

Subfactorial[n] gives the number of permutations of n objects that leave no object fixed.

TransferFunctionExpand[tf] expands polynomial terms in the numerators and denominators of the TransferFunctionModel object tf.

TransferFunctionFactor[tf] factors the polynomial terms in the numerators and denominators of the TransferFunctionModel object tf.

TrigFactor[expr] factors trigonometric functions in expr.

UndirectedGraph[g] gives an undirected graph from the directed graph g.

UndirectedGraphQ[g] yields True if the graph g is an undirected graph and False otherwise.
