erasing particular rows of a vector

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).
