How to convert a string of characters to numbers?

I have the following string obtained from a text file (the text file has a lot of info so I had to go and look for certain lines):
0 0 0 0 0.1 0 0 0 BlaBla
Another line might look like this
1 0.013 0.0156 -0.104 0.0376 0.0624 0.132 0.132 BlaBlaBla
By the way I'm reading the file everything is now a string of characters.
How can I convert that to a vector? Notice that the last column is a string of characters. The white spaces on the first line is different than on the second one too.
Any help is appreciated thanks.

str = '1 0.013 0.0156 -0.104 0.0376 0.0624 0.132 0.132 Bla';
T = regexp(str,'-*\d*\.*\d*','match');
V = cellfun(@str2double,T)

str = '1 0.013 0.0156 -0.104 0.0376 0.0624 0.132 0.132 Bla';
V = sscanf(str, '%g', 6);
