textscan - line by line multiple outputs

I have a text file of the format:

TITLE = "M:/Data2/CTData/fcg1e09/Warwick/Granular/collapse/DVC_Vec_48x48x48_50%ov/ExportDat/D1.dat"

VARIABLES = "x [mm]" "y [mm]" "z [mm]" "u [m/s]" "v [m/s]" "w [m/s]"

ZONE I=83 J=83 K=45

0.891600 147.559402 0.891600 0.000000 0.000000 0.000000

2.674800 147.559402 0.891600 0.000000 0.000000 0.000000

4.458000 147.559402 0.891600 0.000000 0.000000 0.000000 ...

I want to ignore the first 3 lines. I am interested in blocks of 6889 lines where each set of 83 lines needs to write to a row of a matrix (83x83) - a different matrix for each column. I may want to look at a different set of 6889 lines within the text file.

I can't get textscan to work - I assume because it is not designed for multiple outputs. And textread doesn't have fid options and now archaic. So far I have...

%skip 3+6889x lines

for i=1:(3+6889*slice_no),

    fgetl(fid);

end

for j=1:83,

    for k=1:83;

        [X(j,k), Y(j,k), Z(j,k), U(j,k), V(j,k), W(j,k)] = textscan(fid, '%f %f %f %f %f %f');

    end

end

But textscan is failing due to the multiple outputs. Any ideas anyone?

See documentation textscan, Read formatted data from text file or string.

Textscan has one output argument, which capture all output data. Try something like

    C = textscan( fid, '%f%f%f%f%f%f', 83 );

in place of the inner loop
