I have a text file that looks like this. I only need the data under the Px, Py, Pz,... etc header lines. Each set of data is a different number of columns but the same number of rows. How can I filter the text file to only show an array of this data without all the 'Point' information in between and without repeats of the header information? I really don't even need it to display a header since the headers will be the same for every dataset.

In your case you want to parse all lines containing just numbers into an array (which you may later want to split by e.g.: Px = data(:,1) etc.). Providing all data lines hold the same number of entries, this should do the trick:
fid = fopen('Carolyn.txt');
c = textscan(fid,'%s','delimiter','\n');
fclose(fid);
lines = c{1};
data = [];
for i = 1:length(lines)
if ~isempty(lines{i})
parsenumbers = textscan(lines{i},'%f');
numbers = parsenumbers{1};
if ~isempty(numbers) % Line consists of numbers
data = [data;numbers'];
end
end
end
