fill

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 = x0

ri = ri-1 + dxi-1; i=1..n-1
