Dear all,
I have
A=[
0;
2;
34;
45
0;
12;
23;
12;
0;
23]
and I want to erase the rows that contain zero and the element that follows immediately after zero
So I want to erase the elements [0,2], [0,12] and [0,23]
Note that zeros can appear anywhere in the vector. The above vector is a simple example
thanks

indices = find(A==0);
indices = [indices; indices+1]
A(indices) = [];

Look for the index of the elements that are zero. That is to say 'find' them. Once you have them, you know that those index '+1', are the rows that follow. Then remove them (all at once, or backwards).
