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.
