Hi, you can use destructuring to provide defaults. And you can easily curry in options when passing things through.
(defn general-descend [xy ys & {:keys [gradient-fn cost-fn yield-fn alpha iterations thetas] :or {cost-fn cost yield-fn println alpha 0.01 iterations 1000 thetas (matrix 0 (second (dim xs)) 1)}}] ...) (defn special-descend [xs ys & options] (apply general-descend xs ys :cost-fn cost options)) Kind regards Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
