For example, the matrix transposition is simply: (de matTrans (Mat) (apply mapcar Mat list) ) Matrix multiplication (for 2 matrices) in RosettaCode is (de matMul (Mat1 Mat2) (mapcar '((Row) (apply mapcar Mat2 '(@ (sum */ Row (rest) (1.0 .))) ) ) Mat1 ) ) Not sure if this fits your needs ... ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
