A numeric vector expression is an expression whose value is a numeric vector.

You can check the outcomes of the following examples with the calculator.

{ 11, 13, 17 } + 0.5
  adds 0.5 to each element of a vector with three elements, giving a new vector with three elements. Praat writes the outcome to the Info window as three lines, containing the numbers 11.5, 13.5 and 17.5:

`11.5
` `13.5
` `17.5
`

`zero#` (5)
  creates a vector with 5 zeroes. Praat writes them on five lines:

`0
` `0
` `0
` `0
` `0
`

`repeat#` ({ 1, 5 }, 6)
  creates a vector with 12 elements, in which the sequence { 1, 5 } is repeated 6 times. Outcome:

`1
` `5
