This entry uses a non-recursive method for creating Walsh matrices, but the `kprod` definition
at [[Kronecker_product#jq]] could also be used as follows:
<syntaxhighlight lang="jq">
## Generate a Walsh matrix of size 2^$n for $n >= 1
def walshMatrix:
. as $n
| [[1, 1], [1, -1]] as $w2
| if $n < 2 then $w2 else kprod($w2; $n - 1 | walshMatrix) end;
</syntaxhighlight>
<syntaxhighlight lang="jq">
