Find negative values in array, and make them equal to the adjacent values

Hi,
I have a single row array where certain values will become negative. Using this array, I would like to create a new array, but change those negative values to be equal to the ones adjacent to them. What is the best way to do this?
Thanks

Adjacent on which side? And what do you do in case the adjacent ones are also negative?
Here's one way to do it, taking the values of the elements previous to the negative elements regardless of whether those themselves are also negative. (And if the first element is negative it doesn't get changed.)
idx = find(x < 0);
idx(idx == 1) = [];
x(idx) = x(idx-1);
Perhaps you can adapt this to suit your requirements precisely.
