# Algorithm::SpiralMatrix

Various Raku Sequences for spirals in matrix (two-dimensional

arrays).

For overview see [docs/test-output.md](docs/test-output.md) 

and [docs/distance-variants.md](docs/distance-variants.md).

## Synopsis

```raku

use Algorithm::SpiralMatrix;

my $i = 1;

for square_distance(order => 'clockwise') -> ($x,$y) {

    say "{$i++} $x,$y";

    last if $i > 25;

}

```

will print

```
