I want to concatenate two vectors in MATLAB, but I don’t know the correct way to do it. My goal is to create a single vector that combines all the elements of both vectors in the order they are defined.
Here’s what I tried so far:
v1=[1 2 3] v2=[4 5 6] v3=v1 +v2
but the result is v3=[5 7 9] but i wanted v3=[1 2 3 4 5 6]
>Solution :
In MATLAB, the + operator is used for element-wise addition, which is why you’re getting the result [5 7 9]. To concatenate two vectors, you should use square brackets ([]), not the + operator.
Correct way to concatenate vectors:
matlab
Copy code
v1 = [1 2 3];
v2 = [4 5 6];
v3 = [v1 v2]; % Concatenate the vectors
Result:
matlab
Copy code
v3 = [1 2 3 4 5 6]
This will give you the desired result: a single vector that combines all the elements of both v1 and v2 in the order they are defined.
Explanation:
[v1 v2] concatenates the two row vectors v1 and v2 side by side (horizontally). If you wanted to concatenate them vertically, you would use a semicolon between the vectors like this:
matlab
Copy code
v3 = [v1; v2]; % Concatenate vertically (creates a 2x3 matrix)
