Finding the date and time. This gives the current date and time. The Mathematica DateList function returns whatever your computer system gives as the current date and time. ...

AppellF1[a, b_1, b_2, c, x, y] is the Appell hypergeometric function of two variables F_1 (a; b_1, b_2; c; x, y).

EulerPhi[n] gives the Euler totient function \[Phi](n).

The MathLink library provides a collection of C language functions for interacting with Mathematica via MathLink. These functions allow you not only to handle native C data ...

If you have a function defined in an external program, then what you need to do in order to make it possible to call the function from within Mathematica is to add ...

When you do long calculations, it is often convenient to give names to your intermediate results. Just as in standard mathematics, or in other computer languages, you can do ...

Xnor[e_1, e_2, ...] is the logical XNOR (not XOR) function. It gives True if an even number of the e_i are True, and the rest are False. It gives False if an odd number of ...

Combining a new level of programmatic support for symbolic color with carefully chosen aesthetic color parametrizations, Mathematica allows a uniquely flexible and compelling ...

InverseBetaRegularized[s, a, b] gives the inverse of the regularized incomplete beta function.
