I think you have a slight misconception about how to initialise your data sets. Start with this:

data(x,y,6)=zeros(1,1,1);

I think what you mean is this:

data = zeros(x,y,6);

Now, I'm assuming your data files specify a row and column count as the first two values? Is this on the first line? Is every file the same?

In that case you may need to specify the NHEADERLINES parameter for importdata

doc importdata

I'll assume spaces as delimiter and 1 header line:

for n = 1:6
  filename = fullfile(f,a(n+2).name);
  X = importdata(filename, ' ', 1);
  if size(X,1) ~= x || size(X,2) ~= y
    warning( ['Ignoring ' filename ': Wrong dimensions'] );
    continue;
  end
  data(:,:,n) = X;
end

We can only hope that your values for x and y are correct from that call to fileread

Geoff,

The file holds some coordinate informations( 3 columns) and has upto 250 lines of this.

2.8700000e+002 1.1800000e+002 -9.3804749e-001

1.3400000e+002 7.5000000e+001 2.3424967e+000

9.4000000e+001 1.7000000e+001 -7.7416268e-001

9.4000000e+001 2.0700000e+002 -2.1432561e+000

1.0600000e+002 1.7000000e+001 -8.7160374e-001

1.0600000e+002 2.0700000e+002 -2.1432561e+000

1.3300000e+002 1.7000000e+001 -1.1160771e+000

Well,now only the warning is coming up.X is a structure after importdata right? I'm not able to store it in the data(:,:,n) array

[dee koshy]

size of X is (1,1)

X =

data: [405x3 double]

textdata: {'2.8700000e+002' '1.1800000e+002' '-9.3804749e-001'}

colheaders: {'2.8700000e+002' '1.1800000e+002' '-9.3804749e-001'}

What you show is going to give you a problem unless importdata() happens to import exactly one value.

i have to read a dat file in text format. Basically i have to store the values from the dat files into an array of strings or something so that i can compare an input file to this database
