I won't belittle the point about numbered variables. Read Stephen and Jan links. Suffice to say, if you start numbering or naming your variables in any serial manner, you need to stop and rethink.
As said, it's most likely that you don't need a loop. You certainly don't need one for something as simple as averaging even if it's averaging different ranges. But without seeing your code, we can't guess what you're doing exactly.
If your processing code is a script, then first thing you need to do is convert it into a function that accepts either a range vector (eg. the vector 9203:9805 for your first range) or the start and end of the range (eg. 9203 and 9805 for your first range. Once that is done, calling your function for each range is trivial.
ranges = [9203 9805
935596 104564
...
];
result = cell(size(range, 1), 1);
for row = 1:size(ranges, 1)
result{row} = yourfunction(ranges(row, 1), ranges(row, 2));
result{row} = yourfunction(ranges(row, 1):ranges(row, 2));
end
The loop can also be replace by an arrayfun:
ranges = [9203 9805
935596 104564
...
];
result = arrayfun(@yourfunction, ranges(:, 1), ranges(:, 2), 'UniformOutput', false);
But again, it's most likely that none of this needed and you could just use plain indexing if you're just averaging.
