>> ff1='50*z*(z-d)=230.1875*(z^2-r^2)';

>> ff2='((z-d)*r)^2=29318.942*(z^2-r^2)';

>> ff3='50*(z-d)*r=22.0345*(z^2-r^2)';

>> solve(ff1,ff2,ff3)
??? Error using ==> subsref
Index exceeds matrix dimensions.

Error in ==> sym.subsref at 16
y = builtin('subsref',struct(x),a);

Error in ==> solve at 191
S.(char(symvars(j))) = R(:,j);
