:
Range operator.
Syntax
from : to : step
Operands
- from
- The starting point of the range (scalar expression only).
- to
- The end point of the range (scalar expression only).
- step
- The increment (scalar expression only).
Example
| Expression | Result |
|---|---|
1 : 5 : 1 |
{1, 2, 3, 4, 5} |
1 : 2 : 3 |
1 |
2 : -7 : -3 |
{2, -1, -4, -7} |
Comments
The range operator creates a vector or scalar with first element from and incrementing by step until to is reached.
If from + step is greater than to, the result is a scalar. If from + step is less than or equal to to, the result is a vector. The number of points in the result is the greatest integer less than or equal to ((to - from)/step) + 1. The quantity (to - from)/step must be positive and step must be nonzero.
