Filtered by matrix columns

a = this is my maximum
r = is his position
c = new variable if r is validfor 
[a,r]=max(FF);
or i = 1:length(a)-1
   f(i)=0;
      if (r(i) >= r(i+1))
      c(i)=r(i);
      else (r(i) <= r(i+2))
      c(i)=r(i);  
   end
   end

I already asked a similar question, but my task became somewhat more complicated.

The essence of the problem, as I know, is that the first position is correct r (1) = 200, but all the others need to be checked, r (1) is more or less r (2) +50, r (2) = 240, the test passes, then r (2) with r (3), etc. r(3)=700

For reference this is the previous question: comparison of columns in the matrix.

Once again, you've given us code that makes no s, this time it's not even valid. Rather tha explaining what you want with nonsensical code, explain in words and with examples.

What are you trying to do? An example of input and desired output would really help.
