using for loop with if

I cannot manage this code, Iam new please help!!!

r1 = 0.103;

x1 = 1.1;

x2 = 1.13;

xm = 59.4;

v_phase = 400 / sqrt(3);

n_sync = 1500;

w_sync =2*pi*50/2;

v_th = v_phase * ( xm / sqrt(r1 (1) ^2 + (x1 + xm )^2) );

z_th = ((j* xm ) * (r1 + j* x1)) / (r1 (1) + j*( x1 + xm ));

r_th = real(z_th);

x_th = imag(z_th);

for m =1:3

if m==1

r2=0.225;

elseif m==2

r2=0.325;

else

r2=0.425;

end

Ik= v_th/(z_th+(j*x2+r2(m)));

fprintf(' Ik = %.f ' \ ', abs (Ik))

end

fprintf(' Ik = %.f ' \ ', abs (Ik))

Error: A MATLAB string constant is not terminated properly.

Answer 1

[SayedPedram Hosseini]

you havn't defined IK, therefore abs(IK) is unrecognized

besides, in last line you have one( ' ) superfluous. It should be

fprintf(' Ik = %.f  \ ', abs (Ik));

Answer 2

I'm guessing you want a newline at the end?

fprintf(' Ik = %.f \n', abs (Ik))
