Eigenvalues[m] gives a list of the eigenvalues of the square matrix m. Eigenvalues[{m, a}] gives the generalized eigenvalues of m with respect to a. Eigenvalues[m, k] gives ...

VertexInDegree[g] gives the list of vertex in-degrees for all vertices in the graph g.VertexInDegree[g, v] gives the vertex in-degree for the vertex v.

Sequence[expr_1, expr_2, ...] represents a sequence of arguments to be spliced automatically into any function.

ChartElementFunction is an option for charting functions such as BarChart that gives a function to use to generate the primitives for rendering each chart element.

The differential equations that arise in modern applications often have discontinuous coefficients. DSolve can handle a wide variety of such ODEs with piecewise coefficients. ...

"Interrupting Calculations" describes how you can interrupt a Mathematica computation by pressing appropriate keys on your keyboard. In some cases, you may want to simulate ...
