Problem 135. Inner product of two vectors

tricky and conceptual

Was confused for a second, probably because the operation isnt usually called the inner product

It *is* called Inner Product

I didn't know what it meant by "inner product" and that's why I was confused.

字面上只是按下一个键...

简单的

Good problem

我会澄清内部产品。我以前从未听说过它，并且不得不去Google。

好的评论

考虑到，解决完整的随机sudoku被评为介质，这应该很容易标记！

尝试不同的方法，每次显示“断言失败”时，我的结果每次都是正确的。给我提示，以便我可以解决这个问题。

A one-line code... Smart question :) had forgotten about this command.

y =点（x，y）

This example doesn't work, should be z = dot(x,y), or z = sum(x.*y)

Please correct this problem. The output is y when it should be z_correct.

is the problem is correct? do we take output y or z?

LOL @y设置为输出。我差点相信this problem was invalid.

change the output variable to be z

I'm a bit confused. The code outputs the correct answers for the test suite, but it seems I do not pass while submitting.

answer is in terms of z but function give answer in terms of y again confused and give error for simple problem

那里不错的小错误。

该用户（Mohamed Elbesealy）似乎已经为该系统提供了认可，并带有由'Sock-Puppet'帐户提交的这种不明显解决方案的欺诈性“赞”。- div

This is correct. What am I missing?

Eazy Eazy

Why is this smaller than just x*y'?

不仅如此，他的输出是y而不是z！jajaj ...

That is the matrix attribute!

i wrote solution like below
z = sum(x.*y);
它在我的笔记本电脑上工作，但在科迪显示不正确告诉我为什么

嗯，描述有点令人困惑。长度（x）总是=长度（y）吗？它们是NX1还是1xn？无论如何，我提交了几个可能的解决方案（例如z = x'*y，z = sum金宝搏官方网站（x。*y））所有这些都使测试套件失败了...但是它们在我的机器上工作正常！

Note that the output variable in the pattern is y, not z.

ha, yeah. thanks for commenting about that. I didn't see it either.
