hello
you can use sprintf
% Examples
% sprintf('%0.5g',(1+sqrt(5))/2) % 1.618
% sprintf('%0.5g',1/eps) % 4.5036e+15
% sprintf('%15.5f',1/eps) % 4503599627370496.00000
% sprintf('%d',round(pi)) % 3

@Mathieu NOE feel free to move your comment to the answer section, as I would say this is the answer.
@mehmet salihi you can either look at sprintf and fprintf or control the display of values in general with the format function.

I'd use fprintf(), not sprintf(). fprintf() prints directly to the command window while sprintf() sends the result to a string. If you didn't specify a string, it will add "ans = " to the result, or the string variable name if you specified one, and enclose the number in single quote marks.
Compare these 3 different ways of doing it:
val = 0.96875123456789
fprintf('%.5f\n', val); % Method 1 using fprintf
sprintf('%.5f', val) % Method 2 using sprintf without assigning it to anything.
str = sprintf('%.5f', val) % method 3 using sprintf and assigning it to a variable called "str".
Results in command window:
0.96875
ans =
'0.96875'
str =
'0.96875'

Have you read the documentation for sprintf or fprintf?
Note that Matlab stores (and reads) arrays in column-major form, so you might need to transpose your matrix to get the expected result:
A=reshape(1:4,2,2);
disp(A)
fprintf('%d %d\n',A)
fprintf('%d %d\n',A.')
