The precise details of the naming of files differ from one computer system to another. Nevertheless, Mathematica provides some fairly general mechanisms that work on all ...
expr >>> filename appends expr to a file. PutAppend[expr_1, expr_2, ..., " filename"] appends a sequence of expressions expr_i to a file.
QPochhammer[a, q, n] gives the q-Pochhammer symbol (a; q) n.QPochhammer[a, q] gives the q-Pochhammer symbol (a; q) \[Infinity].QPochhammer[q] gives the q-Pochhammer symbol ...
ResetDirectory[] resets the current working directory to its previous value.
HypergeometricPFQ[{a_1, ..., a_p}, {b_1, ..., b_q}, z] is the generalized hypergeometric function \[Null]_p F_q (a; b; z).
RescalingTransform[{{x_min, x_max}, {y_min, y_max}, ...}, {{xp_min, xp_max}, ...}] gives a TransformationFunction that rescales the region with coordinate ranges x_min to ...
CUDAFunctionInformation[fun] returns information about a CUDAFunction.
Clip
(Built-in Mathematica Symbol) Clip[x] gives x clipped to be between -1 and +1. Clip[x, {min, max}] gives x for min <= x <= max, min for x < min and max for x > max. Clip[x, {min, max}, {v_min, v_max}] ...
Mathematica has uniquely flexible capabilities for processing large volumes of textual data. Most often data represented as a string is converted to lists or other constructs ...
