Finding Expressions That Match a Pattern (Mathematica Tutorial)

Finding elements that match a pattern. This gives the elements of the list which match the pattern x^_. Here is the total number of elements which match the pattern.

Atomic Elements of Expressions (Mathematica Guide)

All expressions in Mathematica are ultimately built from a small number of distinct types of atomic elements.

Combinatorial Functions (Mathematica Guide)

$LicenseID (Built-in Mathematica Symbol)

$LicenseID is a string that gives the license ID under which Mathematica is being run.

Mathematica Session History (Mathematica Guide)

The history of an interactive Mathematica computation is both maintained in a fully editable Mathematica notebook, and is stored symbolically in a sequence of In and Out ...

Expression Structure (Mathematica Guide)

A foundational idea in Mathematica is that all expressions—whatever they may represent—ultimately have a uniform tree-like structure.

Applications (CUDALink Tutorial)

Because GPUs are SIMD machines, to exploit CUDA's potential you must pose the problem in an SIMD manner. Computation that can be partitioned in such a way that each thread ...

Fibonacci (Built-in Mathematica Symbol)

Fibonacci[n] gives the Fibonacci number F_n. Fibonacci[n, x] gives the Fibonacci polynomial F_n (x).

Reals (Built-in Mathematica Symbol)

Reals represents the domain of real numbers, as in x \[Element] Reals.

Nand (Built-in Mathematica Symbol)

Nand[e_1, e_2, ...] is the logical NAND function. It evaluates its arguments in order, giving True immediately if any of them are False, and False if they are all True.
