delete rows in Matrix 'A' with same values 'c' in column 'b'
Show older comments
There is a Matrix of variating size, in this case for example 10x4:
A =
|12 1 1 4|
|16 2 1 6|
|8 3 2 6|
|15 4 2 1|
|17 5 2 2|
|1 6 2 3|
|14 7 3 4|
|13 8 3 7|
|12 9 4 6|
|11 10 5 7|
Now I have a look on the 3rd row (because of b=3). The given vector c=[2,4] now says to me which rows to delete in 'A'. If there is a '2' or a '4' in line b=3, then delete this row like this:
A =
|12 1 1 4|
|16 2 1 6|
|14 7 3 4|
|13 8 3 7|
|11 10 5 7|
It must be quite easy, I guess.

b=3;
c=[2 4]
idx=any(ismember(A(b,:),c));
if idx==1
A(b,:)=[]
end
