BellB[n] gives the Bell number B_n. BellB[n, x] gives the Bell polynomial B_n (x).

int MLSetYieldFunction (MLINK link, MLYieldFunctionObject yf) installs the yield function yf for the link referenced by link.

MLYieldFunctionObject is a MathLink type that describes a function pointer to a function taking an MLINK object as an argument and a MLYieldParameters object as an argument ...

Many calculations involve solving systems of linear equations. In many cases, you will find it convenient to write down the equations explicitly, and then solve them using ...

ContourPlot3D[f, {x, x_min, x_max}, {y, y_min, y_max}, {z, z_min, z_max}] produces a three-dimensional contour plot of f as a function of x, y, and z. ContourPlot3D[f == g, ...

! expr is the logical NOT function. It gives False if expr is True, and True if it is False.
