Reading a file with headers and comments textscan

I have a file that looks like this:

(floor 12)
(          x           y            z            u            v            w     diameter            t    mass-flow         mass    frequency         time         name)
(( 4.0331e-01   0.0000e+00   1.3201e+00  -3.1926e-03  -2.9862e-02   2.5690e-02   2.5000e-06   3.0000e+02   0.0000e+00   8.1665e-15   0.0000e+00   5.8257e+02) injection-0:8)

I'd just like the x y z values. I'm using textscan unsuccessfully but am open to suggestions:

[x y z] = textscan (fid, '%n %n %f %f %f %*[^\n]', 'HeaderLines', 2);

I'm not sure how to treat (( . What are the options?

Regards,

Well if it's always (( then the following should work, it will put your 3 values into a cell, hence the myCell{1} to allocate the values if you need them in a seperate variables.

myCell = textscan (fid, '(( %f %f %f %*[^\n]', 'HeaderLines', 2);
x=myCell{1};
y=myCell{2};
z=myCell{3};

You could just call fgets() twice before you call textscan() to skip the headers.
