Currently neither. I have in mind to add some LAPACK bindings (singular value decomposition, eigenvalue decomposition, least squares to begin with). First full native floating point support needs to be implemented. Here is an example of a matrix vector product: (use-modules (aiscm sequence) (aiscm expression) (aiscm tensor)) (tensor i (sum k (* (get (arr (2 3) (5 7)) i k) (get (arr 11 13) k)))) $3 = #>>: (87 124) Floating point values currently fall back on Scheme objects: (tensor i (sum k (* (get (arr (2 3) (5 7)) i k) (get (arr 1.1 1.3) k)))) $4 = #>: (8.7 12.4) Note that in this case the array loops are still JIT compiled. Addition and multiplication are handled by JIT compiling callbacks into GNU Guile (scm_plus, scm_product).
