disp('(a) Solution by mesh analysis')
VL=360*sqrt(3); % Line voltage magnitude
Zs=j*24; Zm=j*6; % Series and mutual impedances
Z= [(Zs-Zm) -(Zs-Zm) 0;
0 (Zs-Zm) -(Zs-Zm); % Matrix from 2 mesh equations
1 1 1 ]; % and one node equation
V=[VL*cos(pi/6)+j*VL*sin(pi/6); % RHS of mesh node equations
VL*cos(-pi/2)+j*VL*sin(-pi/2);
0 ];
Iabc=Z\V; % Line currents, Rectangular
Iabcp=[abs(Iabc), angle(Iabc)*180/pi] % Line currents, polar
Error using horzcat
Dimensions of matrices being concatenated are not consistent.
Error in S10Q6 (line 4)
Z= [((Zs)-(Zm)) -((Zs)-(Zm)) 0;

Just make sure to check the sizes of the variables being concatenated if you encounter similar errors in the future. It's easy to unintentionally expand something into an unexpected size, especially if you're used to older versions.

Ran in:
It means that one or both of Zs or Zm are nonscalar. This works with scalars
Zs = 3;
Zm = 1;
Z= [(Zs-Zm) -(Zs-Zm) 0;
0 (Zs-Zm) -(Zs-Zm);
1 1 1 ]
Z = 3×3
2 -2 0 0 2 -2 1 1 1
If (Zs-Zm) were nonscalar, this concatenation wouldn't work.

So OP has to clear the workspace and run...... j is already defined as vector, it is supposed to be a complex number.
