How to save matrix to .dat file in standard notation

Hi!

I would like to save a binary matrix 'A' to the file 'output.dat' without scientific notation formatting. For instance the matrix A has the (1,1) element, A(1,1) = 0. But it is saved as 0.0000000..e+00, when I'd simply like to to be saved as just 0.

I'm currently using the following basic save function,

A = [0 1 1 0; 0 0 0 1; 1 0 1 0; 0 0 0 0]    % Example binary matrix A
save(['output=' num2str(i+1) '.dat'],'A','-ascii'); 

any help would be greatly appreciated.

Thank you!

You cannot do that using save -ascii: save -ascii uses a fixed format.

Probably the easest way is

filename = sprintf('output=%d.dat', i+1);
dlmwrite(filename, A, ' ' )
