## Examples

    NB. The following functions E1, E2 and E3
    NB. interchange two rows of a matrix,
    NB. multiply a row by a constant,
    NB. and add a multiple of one row to another:

    E1=: <@] C. [
    E2=: f`g`[}
    E3=: F`g`[}
    f=: {:@] * {.@] { [
    F=: [: +/ (1:,{:@]) * (}:@] { [)
    g=: {.@]
    M=: i. 4 5
    M;(M E1 1 3);(M E2 1 10);(M E3 1 3 10)

    NB. Implementation of quicksort

    sel=: adverb def 'u # ['

    quicksort=: verb define
      if. 1 >: #y do. y
      else.
        (quicksort y <sel e),(y =sel e),quicksort y >sel e=.y{~?#y
      end.
    )

    NB. Implementation of quicksort (tacit programming)

    quicksort=: (($:@(<#[), (=#[), $:@(>#[)) ({~ ?@#)) ^: (1<#)
