Create a vector with equally spaced elements:
- Usage 1
fill(n {, x0 {, dx}})- n
- vector length, a scalar (>0)
- note: if n is a vector, ncol(n) is used as number of elements
- x0
- start value, must be a scalar (default=0)
- dx
- increment, must be a scalar (default=0)
- Result 1
- The result is a vector r with n elements. The elements are initialized with:
ri = x0 + i*dx; i=0..n-1
Create a vector with variable increment:
- Usage 2
fill(n , x0 , dx)- n
- vector length, a scalar (>0)
- note: if n is a vector, ncol(n) is used as number of elements
- x0
- start value, must be a scalar
- dx
- increment, must be a vector with at least n-1 elements
- Result 2
- The result is a vector r with n elements. The elements are initialized with:
r0 = x0ri = ri-1 + dxi-1; i=1..n-1
