Many Yorick calculations begin by defining an array of *x *values
which will be used as the argument to functions of a single variable. The
easiest way to do this is with the `span` or `spanl` function:
` x = span(x_min, x_max, 200);`

This gives 200 points equally spaced from `x_min` to `x_max`.

A two dimensional rectangular grid is most easily obtained as follows:
` x = span(x_min, x_max, 50)(, -:1:40);`
` y = span(y_min, y_max, 40)(-:1:50, );`

This gives a 50-by-40 rectangular grid with `x` varying fastest.
Such a grid is appropriate for exploring the behavior of a function of
two variables. Higher dimensional meshes can be built in this way, too.
