So I currently have text files that look like this for example, but can go on for a lot longer:
14 2.649 5.000 93.5020 -61.9602 2.5000 90.5132 -64.4065 2.5000 88.3552 -67.5184 2.5000 87.8311 -70.6759 2.5000 88.0976 -74.0126 2.5000 90.2142 -75.7097 2.5000 92.9562 -77.3048 2.5000 95.6058 -75.8448 2.5000 98.5412 -74.1425 2.5000 99.7479 -70.8020 2.5000 100.8159 -67.0142 2.5000 100.0439 -63.0305 2.5000 98.6425 -58.8215 2.5000 95.7429 -55.5767 2.5000
#
14 2.040 5.000 -79.9068 55.3230 2.5000 -84.3332 53.5374 2.5000 -88.8590 51.4109 2.5000 -93.3437 49.3544 2.5000 -97.6597 47.7654 2.5000 -101.6949 47.0018 2.5000 -105.5733 47.2205 2.5000 -108.7795 48.8558 2.5000 -111.8250 51.5986 2.5000 -114.0240 55.1797 2.5000 -116.2758 59.4346 2.5000 -118.2519 63.7965 2.5000 -120.4604 68.1404 2.5000 -122.8527 71.9415 2.5000
and the goal is to make it so that the first set of numbers is reordered like this:
14.000000 2.649000 5.000000
93.502000 -61.960200 2.500000
90.513200 -64.406500 2.500000
88.355200 -67.518400 2.500000
87.831100 -70.675900 2.500000
88.097600 -74.012600 2.500000
90.214200 -75.709700 2.500000
92.956200 -77.304800 2.500000
95.605800 -75.844800 2.500000
98.541200 -74.142500 2.500000
99.747900 -70.802000 2.500000
100.815900 -67.014200 2.500000
100.043900 -63.030500 2.500000
98.642500 -58.821500 2.500000
95.742900 -55.576700 2.500000
and placed into a new text file, then have matlab read the '#' and open another new file to do the same thing with the second set of numbers.
Any help is appreciated, especially similar examples.

It might help if you post one of the text files, or a subset of the file.

This can probably be streamlined, but I think it achieves what you are looking for:
% read the test data into a 1x1 cell and convert to string array
fid = fopen('testdata.txt'); % data you posted
C = textscan(fid, '%s');
fclose(fid);
s = string(C{:});
% find indices of hash delimiters
idx = [0; find(strcmp(s(:), '#'))];
% pull data between delimiters, reshape, write to output file
k = 1;
for i=2:length(idx)
s1 = s(idx(i-1)+1:idx(i)-1);
s2 = reshape(s1,3,[])';
filename = sprintf('somefile%d.txt', k);
writematrix(s2,filename);
k = k+1;
end

OK, yes. There was a bug in the reshaping. I just edited the answer with a fix. Try again, please.
