MATLAB: How to tabulate complex numbers using fprintf

complex numberstabulating

Hi All,
I have some results in complex form. I want to tabulate these results by using fprintf but I just get the real parts of numbers on my command window. Here is my code:
g=@(x)x^4-(0.4982*x^3)+(2.7464*x^2)-(1.1146*x)+(2.6699)
dgdx=@(x)(4*x^3)+(1.4946*x^2)+(5.4928*x)+(1.1146)
x0=1+i
x=x0
it_no=0
fprintf('\n\n%18s%18s%18s\n','it_no','x','g(x)');
while 1
    it_no=it_no+1;
    xprev=x;
    x=xprev-(g(x)./dgdx(x));
    if abs(g(x))<10^-4;
        break
    end  
    fprintf(' %17.0f\t %17.7f\t %17.7f\t\n',[it_no,x,g(x)]);
end
fprintf(' %17.0f\t %17.7f\t %17.7f\t\n',[it_no,x,g(x)])
How can I tabulate both real and imaginary parts of complex numbers using fprintf? Anyone to help me for this problem?
I'll appreciate for any help.
Thanks Already!

You have to separate the real and imaginary parts and print them individually. See if replacing your fprintf statements with this one produces the results you want:
fprintf(' %17.0f\t %17.7f %11.7f*i\t %17.7f %11.7f*i\t\n',[it_no,real(x),imag(x),real(g(x)),imag(g(x))])
