fill
Create a vector with a linear function.
Usage:
fill(n, d, k)
Parameters:
- n
- The number of elements. There is no default.
- d
- The start value. The default is
0.
- k
- The increment step value. The default is
0.
Result:
The result is: x[i = 0..n-1] = d + i*k
Notes:
If n is a vector, the length of the vector is used.
Create a vector with equally spaced elements.
- Usage
fill(n{, x0{, dx}})- n
- vector length, a scalar (>0)
- note: if n is a vector, ncol(n) is used as number of elements
- x0start value, must be a scalar (default=0)
- dxincrement, must be a scalar (default=0)
