To get meshgrid style, x and y shall be swapped as

```
xv = getindex.(Iterators.product(y, x, z), 2)
yv = getindex.(Iterators.product(y, x, z), 1)
```

However, if you really need this, by far the easiest and fastest I’ve tested is list comprehension:

```
function meshgrid(x, y)
X = [x for _ in y, x in x]
Y = [y for y in y, _ in x]
X, Y
end
function meshgrid2(x, y)
X = getindex.(Iterators.product(y, x), 2)
Y = getindex.(Iterators.product(y, x), 1)
X, Y
end
x = 1:1000
y = 1001:2000
```
