QUESTION
Write a program called ‘vectormath.py’ to do basic vector calculations in 3 dimensions: addition, dot product and normalization.
There's an error on my mapping function.
sample input:
...ANSWER
Answered 2021-May-29 at 05:19Replace
vector_A = map(int,vector_A) with vector_A = list(map(int, vector_A))
and
vector_B = map(int,vector_B) with vector_B = list(map(int, vector_B))
Here map(int, vector_A) returns a map object which is an iterator.
list() takes the iterator and returns a list which you require in your code for further vector calculation.
As of now, you are passing map object to functions addition, Dotproduct and norm, which actually should be a list for the calculations defined.
Above changes converts the map object to list.
QUESTION
so i want to create a vectormath program, that has 3 calculation dimensions. addition(addition of vectors) dot( the sum of the products) normalization(the norm of a single vector is the square root of the sum of the squares)
if i have 2 vectors: A = (1,3,2) B = (2,3,0)
Addition: A + B = (1 + 2, 3 + 3, 2 + 0) = (3,6,2)
Dot: A.B = 1.2 + 3.3 + 2.0 = 2 + 9 + 0 = 11
Norm (of A): A = Sqrt(1^2 + 3^2 + 2^2) = Sqrt(14) = 3.74
B = Sqrt(2^2 + 3^2 + 0^2) = Sqrt(4+9+0) = Sqrt(13) = 3.61

QUESTION
I'm trying to cram brush up on Scala for a job I got, and I'm looking into implicit classes. So far they seem quite handy in making code more readable, but I've run into a problem that I can't figure out.
In this code, I'm implementing some common vector operations, and for the most part they seem to be running just fine. However, when I added the norm method, the magn method started throwing errors. My operating script is thus:
ANSWER
Answered 2018-Jan-26 at 20:47Postfix notation (dot-less) can be used when the method takes no argument, but you have to help the compiler figure it out.
QUESTION
Just started getting this error, The same field name is serialized multiple times in the class or its parent class. This is not supported: Base(ICEWorldPathfindingAdapter) m_Transform from the code below.
I went to the variable m_Transform and changed it from protected Transform m_Transform; to protected new Transform m_Transform; but that ended up throwing more errors. I'm unsure how to track down and the solve this issue. Any help here would be greatly appreciated. Thank you.
ANSWER
Answered 2017-Dec-14 at 22:13Helpful answer: Don't bother with optimizing transform access. It's not simple GetComponent() since Unity 5.x.
in Unity5 we also cache the transform component on the c# side, so there should no longer be a performance reason to cache the transform component yourself.
Lazy answer: Rename your m_transform variable.
Some speculation on why this is happening since Unity team did not provide us with it's serialization system source code:
Apparently, Unity stores cached transform in the field with the name "m_transform" (it fits code style of Unity team). Apparently, it compares fields simply by name to prevent collisions and does not take into account if it can be serialized in a first place. Another example of that problem could be found here.
By the way, Unity serialization is done with reflection. Further read.

...ANSWER
Answered 2017-Jul-20 at 18:53You don't initialize int *p_result; anywhere. You're passing in the value of an unitialized pointer to your distance routine. That local copy is set to point at a local array, but after that function call the p_result in your main function is still uninitialized.

Install vectormath
You can use vectormath like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
