How to save this matrix?

I have 12 columns in matrix:

For example:

6,2713	1,0876	23,3585	31,5388	51,1182 27,1688	9,6255	0,7503	0	0	0	0,3299	-5,8128	-37,5098
6,0273	1,0467	22,9448	31,1567	48,5899	26,2585	9,6405	0,7245	0	0	0	0,3299	-5,8173	-37,5098
5,6551	0,9194	22,7827	29,8986	47,5964	24,7148	9,7817	0,6674	0	0	0	0,3299	-5,8217	-37,5098

How to save this matrix with fprintf for txt file?

I tried

fileID = fopen('test.txt','w');
fprintf(fileID,'%.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f %.4f\n',[a,b,c,d,e,f,g,h,i,j,k,l,m,n];

If there's just one array/matrix M, then

fid=fopen('test.txt','w');
fmt=[repmat('%.4f',1,size(M,2)) '\n'];            % build format string
fprintf(fid,fmt,M.')                              % write -- NB: to transpose 
fid=fclose(fid);

But, I'd recommend using one of the higher-level routines instead of the low-level i/o unless the desired file format is one that can't be written otherwise. See

doc writematrix

and friends...
