MATLAB: Change elements by a set amount.

integer fun

I have a vector that goes up in twos:

delta= 2 2 4 4 6 6

What function can I use so that:

delta= 2 2 3 3 4 4 ?

Justin, do you mean

 delta = delta - delta/2 + 1

MATLAB: How to get the final number of lines in a data file

count = 0;
while true
  if ~ischar( fgetl(fid) ); break; end
  count = count + 1;
end
fclose(fid)
title(sprintf('lines in file = %d', count));

Note that feof(fid) never predicts end of file. feof() is never true unless you have already tried to read after the end of file, so even with a completely empty file, feof() would not immediately be true.

You can tell you have reached end of file when fgetl() returns something that is not a character.

                 if t<=s1(1,n)
                      w = ((2695-6169)/(32.2-0))*dt + 6169;
                  elseif t>s2(1,n)
                      w = 100;
                      T = 0;
                    else
                      w = ((397 - 2082) / (138.2 - 32.2)) * dt + 2082;
                      T = 3973;
                end

The dt coded above is timestep, which is wrong if should be (t-s1) or (t-s0)
