man... I have read fileparts command, and i just can't do it... I am in a hurry right now..
I have files named such as 1.0 f.txt, 1.5 f.txt, 1.6 f.txt, 2.0 f.txt .... so on.
I want to fprintf or print only the numbers from the file name, such as 1.0, 1.5, 1.6, 2.0... so on.
I guess I have to use fileparts command, but don't quite understand how to separate the numbers, space, words, and extension..
Can anyone give me simple example or solution to this?

If "filename" is the name of the file, then
parts = strsplit(filename, ' ');
and then parts{1} would be the string up to (but excluding) the space.
fprintf('The parameter value was: %s\n', parts{1})

strsplit was added in R2013a. If you are using a MATLAB older than that then you need to indicate which version so that we can avoid wasting our time proposing solutions that cannot work for your version.
On the other hand,
idx = find(filename == ' ', 1, 'first');
part1 = filename(1:idx-1);
fprintf('The parameter value was: %s\n', part1);
