Hello
My name is Atenea . I just want to ask you that how can i Creat a program that just say "hello word" and another that can add a "matrix" if you can help me I would really going to apreciate please. Thank you for your listening
It depends if your matrix is represented as a list of lists or a two-dimensional array. For lists it is something like that: plus (a,b) = a+b plus_vec ([],[]) = [] plus_vec (a:as,b:bs) = (plus (a,b)):(plus_vec (as,bs)) vector_add a b = (map plus (zip a b)) matrix_add a b = (map plus_vec (zip a b)) It can be done a bit better using classes, but then it will be less easy to understand. For 2-D arrays, I believe there is an example in the tutorial that shows matrix _mulitplication_, so addition should be quite trivial after understanding that.
