Hello, my question is simple and please I request a simple answer, How to convert a big table of data .mat to a text file preserving the same size? I can't give names of variables it's just a matrix full of numbers, the size is bigger than 1000, Thanks in advance!

The question is a little bit vague. I guess, you want something like this:
Data = load('FileName.mat');
DataField = fieldnames(Data);
dlmwrite('FileName.txt', Data.(DataField{1}));

( 0.250000 0.666667 )

@SUSHMA MB: Please do not append new questions as comment to answers of a different question. Open a new thread instead. Note that the readers cannot know, what "the .mat file" is.
Most likely the answer will be easy:
data = rand(10, 2); % Perhaps this is the contents of the MAT file
fid = fopen(FileName, 'w');
if fid==-1, error('Cannot open file: %s', FileName); end
fprintf(fid, 'x={\n');
fprintf(fid, '( %.6f %.6f )\n', data.');
fprintf(fid, '}\n');
fclose(fid);
Do you see the problem? Now you cannot accept the answer and further comments will confuse the readers, because it is unclear, if they concern the original or your question. Therefore such "thread-highjacking" is not wanted.

Follow the related question that I asked. Save workspace to m-file. Basically use Simulink.saveVars if you have it.
