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)

Result: The result is a vector r with n elements. The elements are initialized with: r_i = x0 + i * dx; i=0..n-1

-=====fill=====
-Create a vector with a linear function.
-=====Usage:=====
-<code>fill(<var>n</var>, <var>d</var>, <var>k</var>)</code>
-=====Parameters:=====
-;<var>n</var>
-:The number of elements. There is no default.
-;<var>d</var>
-:The start value. The default is <code>0</code>.
-;<var>k</var>
-:The increment step value. The default is <code>0</code>.
-=====Result:=====
-The result is: x[i = 0..<var>n</var>-1] = <var>d</var> + i*<var>k</var>
-=====Notes:=====
-If <var>n</var> is a vector, the length of the vector is used.
