Extracting X and Y binary data to simple X Y file

I am trying to extraxt X and Y coordinates form a binary file.

I want to generate a text file X and Y cordinates in every itteration.

I tried this code:

delete shape_*.dat;
for i=1:numel(SX)
%sx1 = SX{i};
%sy1 = SY{i};
filename = sprintf('shape_0%d.dat', i);
%dlmwrite(filename,SX{i})
dlmwrite(filename,{SX{i},SY{i}},'Delimiter','\t')
end

Attached how it looks like SX and SY.

So the code generete something like that:

SX{i} SY{i}

Which means it put all the values of SX{i} then all the values of SY{i}.

but i want for example, the first colum of SX{1,1} be with the first colum of SY{1,1} and so one.

And save the file for every i.

We can do nothing with images -- attach a short section of the input file and then explain clearly what it is you expect.

SX = readArray('sx.afdat');
SY = readArray('sy.afdat');

and those plus your attached results don't seem to have anything at all to do with a 'binary' file -- that would appear to be an ordinary text file...what's up with "binary"?

The input files are very large,

But the images are showing indeed what containe the input file (SX and SX).

You can see that SX and SX are like matrixes size (1003x1) with cells of dimensions (117x90).

I just want to have a file with X Y coordinates for every step

for example:

881.395017137202 191.319844359188 392.188873596697 271.034002421179

881.240268490015 191.966052698394 392.614416558883 271.540473556606

881.097198679310 192.614050849855 392.985303204938 272.087729560085

It looks like

X1_1 Y1_1 X1_2 Y1_2

X2_1 Y2_1 X2_2 Y2_2

X3_1 Y3_1 X3_2 Y3_2

vals = permute( cat(3, SX{K}, SY{K}), [1 3 2]);

vals is now a something-by-2-by-something array; in particular, 117 x 2 x 90. The first column is X and the second column is corresponding Y. The hyperplanes correspond to the x 90

It is not obvious to me how you want to represent pairs of columns for a 2D array. Perhaps you want to continue on to

vals = reshape(vals, size(vals,1), []);

That would give you 117 x 180 with alternating columns being X and Y.

Thank you very much! it works!
