Concise vector adding in Python? - Stack Overflow
2015年5月1日 · I often do vector addition of Python lists. Example: I have two lists like these: a = [0.0, 1.0, 2.0] b = [3.0, 4.0, 5.0] I now want to add b to a to get the result a = [3.0, 5.0, 7.0]. Usually...

python - Element-wise addition of 2 lists? - Stack Overflow
2013年9月10日 · So, the algorithmic complexity of most of these solutions are Big-O(n). Where n is the dimension of the vector. So, from an algorithmic point of view, using a for loop to iteratively generate the resulting list is logical and pythonic too. However, in addition, this method does not have the overhead of calling or importing any additional library.
Overloading Addition, Subtraction, and Multiplication Operators
2017年4月6日 · How do you go about overloading the addition, subtraction, and multiplication operator so we can add, subtract, and multiply two vectors of different or identical sizes? For example, if the vectors are different sizes we must be able to add, subtract, or multiply the two vectors according to the smallest vector size?
Adding two vectors in Python 3 using the __add__ method
2019年5月1日 · I want to add two vectors with n dimensions using the __add__ method. The elements of the 2 vectors will be input by the user. I don't understand how to define the vector as a single object.
Triangle law of vector addition - Mathematics Stack Exchange
2019年7月2日 · Why does the triangle law of vector addition work, at all? The triangle law follows directly from the defining axioms of vectors*. Suppose you have three vectors such that $\vec a + \vec b = \vec c$ .
With regards to vector spaces, what does it mean to be 'closed …
A vector space is an abelian group under addition, so is special case. And there are less well-behaved operations which may not have inverses, or be associative, which are nonetheless "closed" under an operation in the sense that taking two objects and applying the operation leads to another object of the same kind. $\endgroup$
Unsigned logic, vector and addition - How? - Stack Overflow
2011年4月17日 · In brief, you can add the ieee.numeric_std package to your architecture (library ieee; use ieee.numeric_std.all;) and then do the addition using: Output <= std_logic_vector(unsigned(Output) + 1); to convert your std_logic_vector to an unsigned vector, increment it, and finally convert the result back to an std_logic_vector.
python - Numpy vector and matrix addition - Stack Overflow
2021年3月7日 · What is the best way to perform normal vector addition, where one of the operands is an n x 1 matrix? Why do I care? Sometimes, a function that should return a vector returns an n x 1 matrix (because the function would equivalently work element-wise on a matrix). When I want to further work with the returned "vector", I always have to reshape ...
