ArrayTools

 Append
 append an element to an Array

 Calling Sequence Append(A,expr,opts)

Parameters

 A - : Array or Vector expr - : expression to append opts - : (optional) inplace=true or inplace=false

Options

 • inplace : keyword option of the form inplace=true or inplace=false. This specifies whether the append operation should reuse the existing Array or generate a new Array.  Its default value is true.

Description

 • The Append(A,expr) command appends the expression expr to the end of the Vector or the 1-D Array, A.
 • When inplace=false is specified, the append operation allocates a new Array and does not modify the existing one.  Otherwise, the existing object is modified.
 • This function is part of the ArrayTools package, so it can be used in the short form Append(..) only after executing the command with(ArrayTools). However, it can always be accessed through the long form of the command by using ArrayTools[Append](..).

Examples

 > $\mathrm{with}\left(\mathrm{ArrayTools}\right):$
 > $A≔\mathrm{Array}\left(\left[2,3,5\right]\right)$
 ${A}{≔}\left[\begin{array}{ccc}{2}& {3}& {5}\end{array}\right]$ (1)
 > $\mathrm{Append}\left(A,\frac{1}{x}\right)$
 $\left[\begin{array}{cccc}{2}& {3}& {5}& \frac{{1}}{{x}}\end{array}\right]$ (2)
 > $\mathrm{Append}\left(A,\mathrm{sin}\left(x\right)\right)$
 $\left[\begin{array}{ccccc}{2}& {3}& {5}& \frac{{1}}{{x}}& {\mathrm{sin}}{}\left({x}\right)\end{array}\right]$ (3)
 > $v≔⟨1,2x⟩$
 ${v}{≔}\left[\begin{array}{c}{1}\\ {2}{}{x}\end{array}\right]$ (4)
 > $\mathrm{Append}\left(v,3{x}^{2},\mathrm{inplace}=\mathrm{false}\right)$
 $\left[\begin{array}{c}{1}\\ {2}{}{x}\\ {3}{}{{x}}^{{2}}\end{array}\right]$ (5)
 > $v$
 $\left[\begin{array}{c}{1}\\ {2}{}{x}\end{array}\right]$ (6)

Compatibility

 • The ArrayTools[Append] command was introduced in Maple 18.
