Here is one way:

fid_in  = fopen('text_in.txt');
fid_out = fopen('text_out.txt','w');

text_in = fgetl(fid_in);
while ischar(text_in)
    text_out = [regexprep(text_in,' ','')];
    fprintf(fid_out,'%s\n',text_out);
    disp(text_in)
    disp(text_out)
    text_in = fgetl(fid_in);
end

fclose(fid_in);
fclose(fid_out);

I tested it on the attached file.

Here is a fast solution in just three lines:

>> fid = fopen('text_out.txt','wt');
>> fprintf(fid,'%s',strrep(fileread('text_in.txt'),' ',''))
>> fclose(fid);
