PowersRepresentations[n, k, p] gives the distinct representations of the integer n as a sum of k non-negative p\[Null]^th integer powers.

BoxRatios is an option for Graphics3D that gives the ratios of side lengths for the bounding box of the three-dimensional picture.

SortBy[list, f] sorts the elements of list in the order defined by applying f to each of them.

Suppose that you have a limited amount of data from which to obtain estimates of statistics for a population. The sampling distribution for those estimates can be ...

Mathematica provides powerful functions to compute state-feedback and estimator gains using pole-placement or optimal techniques. In addition, it has functions that directly ...

Mathematica provides state-of-the-art fully automated visualization of vector functions and data—suitable for representing flows, field lines and other vector fields of any ...

Mathematica makes it easy to take even the most complicated derivatives involving any of its huge range of differentiable special functions.

Mathematica represents vectors as lists, and never needs to distinguish between row and column cases. Vectors in Mathematica can always mix numbers and arbitrary symbolic or ...

Quotient[m, n] gives the integer quotient of m and n. Quotient[m, n, d] uses an offset d.

Functions in Mathematica are carefully set up so that you normally do not have to know how they work inside. But particularly for numerical functions that use iterative ...
