contains also the size.
I would do this with some logical indexing magic.
a=[0.0 0.0 0.3 0.4 0.5 0.0 0.0 0.0 0.0 1.0 1.1];
step = 0.1;
tmp = a>0;...
Have a look at fzero.
You can easily modify your equation to the one in the example.
Sounds like a textbook example for hough transform.
Look at: <http://en.wikipedia.org/wiki/Hough_transform>
well in some way you will have to use isnan. You could use |bwconncomp| to find "lonely" Nans. Like in this example:

I also only see the trivial solution C(z,t) = 0
But let me take some notes and see if a something more general is possible.

If you want with laying back you could get random indices with:
ind = randi(1e6,1e4,1);
xout = x(ind);
One thing that happens often to me is that I forget to close invisible windows. (created by figure('visible','off') )
I would do that by nested for loops:

Maybe the predefined commands will suffice.

did you try replacing the apostrophes with ''(2 apostrophes) or " ?

You can do the splitting with regexp.
It will look like:
