NSolve[expr, vars] attempts to find numerical approximations to the solutions of the system expr of equations or inequalities for the variables vars. NSolve[expr, vars, ...

GraphQ[g] yields True if g is a valid Graph object and False otherwise.

FindThreshold[image] finds a global threshold value that partitions the intensity values in image into two intervals.

Different kinds of vector and matrix multiplication. This multiplies each element of the vector by the scalar k. The "dot" operator gives the scalar product of two vectors.

DirectedGraph[g] gives a directed graph from the undirected graph g.DirectedGraph[g, conv] gives a directed graph using the conversion conv.

SubMinus[expr] displays as expr_-.

SubPlus[expr] displays as expr_+.

AnimationCycleOffset is an option for cells that specifies the relative position of the next graphic to be used in an animation sequence.
