mlint64 is a MathLink type for storing 64-bit integers.

When Mathematica transforms an expression such as x+x into 2x, it is treating the variable x in a purely symbolic or formal fashion. In such cases, x is a symbol which can ...

NFourierTransform[expr, t, \[Omega]] gives a numerical approximation to the Fourier transform of expr evaluated at the numerical value \[Omega], where expr is a function of t.

NInverseFourierTransform[expr, \[Omega], t] gives a numerical approximation to the inverse Fourier transform of expr evaluated at the numerical value t, where expr is a ...

SQLConnections[] returns a list of the open SQLConnection objects.

SQLResultSets[] returns a list of the open SQLResultSet objects.

Biharmonic[f] gives the biharmonic, \[Del]^4 f, of the scalar function f in the default coordinate system. Biharmonic[f, coordsys] gives the biharmonic of f in the coordinate ...
