What happened to my solver script?

I am studying the calculation of GPS coordinates. I am expecting matlab giving me the origin and zero clock offset. However Matlab hangs and unable to solve.
syms x y z t sv1 = [1 0 0]; sv2 = [0 1 0]; sv3 = [0 0 1]; sv4 = [1 1 1]; prange = [1 1 1 sqrt(3)];
pos = solve( ... '((x-sv1(1))^2 + (y-sv1(2))^2 + (z-sv1(3))^2)^0.5 + t = prange(1)', ... '((x-sv2(1))^2 + (y-sv2(2))^2 + (z-sv2(3))^2)^0.5 + t = prange(2)', ... '((x-sv3(1))^2 + (y-sv3(2))^2 + (z-sv3(3))^2)^0.5 + t = prange(3)', ... '((x-sv4(1))^2 + (y-sv4(2))^2 + (z-sv4(3))^2)^0.5 + t = prange(4)', x, y, z, t);

Don't pass char vectors into solve. If you're using release R2012a or later, use == to create your equations. We started warning about passing char vectors into solve in release R2015a, according to the Release Notes.
