how to increase the decimal place and it must be side to side as below

The matrix is not strictly diagonally dominant at row 1(ignore this)

 approximated,      exact= 
 0.18221-0.73861i            0.18233-0.73524i 
 0.0032185-0.22997i        0.0022028-0.22863i 

========================================

answer of my code is below it must be like the above answer

approximated=

0.1822 - 0.7386i

0.0032 - 0.2300i

exact=

0.1823 - 0.7352i

0.0022 - 0.2286i

=============================================

Answer 1

[dpb]

fmt=['%0.4f%+0.4fi\t%0.4f%+0.4fi\n'];

>> for i=1:size(approx,2)
     fprintf(fmt,real(approx(i)),imag(approx(i)),real(exact(i)),imag(exact(i)))
    end
0.1822-0.7386i	0.1823-0.7352i
0.0032-0.2300i	0.0022-0.2286i
>> 

Will leave adding header line as exercise...
