Reading formatted data from a file

I have a file containing data like:

Blocks=N

The position is -8,5, velocity is 1 and direction is 0 deg

1.7 2 3 4
5 6.2 7 8
9 0 1 2.4
3 4 5 6.2

The position is -8,10, velocity is 1 and direction is 5 deg

5.2 8 9 4
1 5 7 4.1
4 9 6 3
8 2 4 6

and so on..... till.... N

To read this data I am using:

inputfile1=sprintf('AmbgFunc for all positions all velocities'); 
fid=fopen(inputfile1,'r');
blocks_ip = fscanf(fid, 'blocks=%d\n', 1);
for i=1:blocks
  mystruct(i).position = fscanf(fid, '%*s %*s %*s %f,%f, %*s %*s %f %*s %*s %*s %f %*s\n', 4)';
  position=mystruct(i).position 
  mystruct(i).Matrix  = fscanf(fid, '%f', [4,4])';   
  Mat(:,:,i)=mystruct(i).Matrix
end

It's correctly reading the position from the header which is [-8,5 1 0] but it is not reading the matrix and hence in the second loop the position is read wrong (one of the matrix value is read instead). Any help would be appreciated. Thanks
