subtracting a value from a vector
显示 更早的评论
Hello I have a 10*1 vector like A=[3,4,5,6,7,8,9,2,4,3]. I want to subtract all the elements of this vector by another 1*1 vector B=[5].
A-B doesn't work to give me [-2,-1,0,1,2,3,4,-1,-2]. How can I do this?

Maybe you mean: how to remove the element in B from A
A=[3,4,5,6,7,8,9,2,4,3]
B=3
out=setdiff(A,B)

Wow, that doesn't "work to give me [-2,-1,0,1,2,3,4,-1,-2]." but apparently your answer is what he wanted. Did you get an advance copy of the Mind Reading Toolbox? :-)

No, it will give this:
A =
3 4 5 6 7 8 9 2 4 3
B =
5
C =
-2 -1 0 1 2 3 4 -3 -1 -2
If you want to remove the -3 element like you have in your desired result , there are a couple of ways you can do that:
C(8) = []; % Remove the -3
C(end-2) = []; % Remove the -3
C(C == -3) = []; % Remove the -3
