delta
The difference between the first and last points of a vector.
Syntax
delta(vector)
Argument
- vector
 - The vector expression.
 
Example
| Templex Expression | Result | 
|---|---|
{delta({3, 5, 7, 9})} | 
                                6 | 
                            
{delta(4, 3, 2, 1, 0)} | 
                                4 | 
                            
{delta(cos(0:(2*PI):(PI/24))} | 
                                0 |

Comments
The result is the difference between the first and last element of a vector. Only the first and last elements in the vector are compared, even though other elements might have lesser or greater values.
