Algebraic Transformations (Mathematica Guide)

Mathematica includes functions for performing a variety of specific algebraic transformations. Some are algorithmically straightforward; others include highly sophisticated ...

Applying Functions to Lists (Mathematica Guide)

Many computations are conveniently specified in terms of applying functions in parallel to many elements in a list. Mathematica provides a suite of elegant functional ...

Parts of Expressions (Mathematica Guide)

Mathematica's unified symbolic architecture allows immediate generalization of part-oriented list operations to arbitrary expressions —supporting operations both on ...

Close (Built-in Mathematica Symbol)

Close[stream] closes a stream.

StreamPosition (Built-in Mathematica Symbol)

StreamPosition[stream] returns an integer that specifies the position of the current point in an open stream.

WriteString (Built-in Mathematica Symbol)

WriteString[channel, expr_1, expr_2, ...] converts the expr_i to strings, and then writes them in sequence to the specified output channel.

InputStream (Built-in Mathematica Symbol)

InputStream["name", n] is an object that represents an input stream for functions such as Read and Find.

OutputStream (Built-in Mathematica Symbol)

OutputStream["name", n] is an object that represents an output stream for functions such as Write.

Streams (Built-in Mathematica Symbol)

Streams[] gives a list of all streams that are currently open. Streams["name"] lists only streams with the specified name.

ErrorBox (Built-in Mathematica Symbol)

ErrorBox[boxes] is a low-level box construct that represents boxes that cannot be interpreted in input or output.
