问题描述
美好的一天,我在序言中进行算术问题,是的,它是我搜索过的点积,发现一堆乱码与本书所要问的内容并不相等.它是/3,所以这是我到目前为止的结果,但我需要对两个列表的乘积结果求和.关于应该建议做什么的任何提示?
Good Day I am doing the problema of arithmetic in prolog and Yes its the dot Product I have Searched and found a mess of code that did not equal to what the book is asking me. Its a /3 so this is what i have so far but i need to sum the result of the product of both list. Any hint on what should be recommended to do?
dot([HD|TL],[HD2|TL2],Result):- Mul is HD2 * HD, dot(TL,TL2,Mul), Result is Mul + Reuslt2. dot([],[],0).推荐答案
您的问题是,您两次使用Mul表示您打算一次使用它,而Reuslt2在任何地方都不存在.可能您的意思是:
Your problems are that you're using Mul twice where you mean to use it once, and Reuslt2 doesn't exist anywhere. Probably what you mean is:
dot([], [], 0). dot([H1|T1], [H2|T2], Result) :- Prod is H1 * H2, dot(T1, T2, Remaining), Result is Prod + Remaining.更多推荐
