MATLAB: Solve function (and other code help)

MATLABsolve function

I wish to find what Z is at these heights, so I looked up the code for it S = solve(eqn,var)
Z = solve(Re.*Z/Re.+Z=.hi, Z)
hi = [0 , 11 , 20, 32 , 47, 51 , 71 , 84.852 , 90 ]
Re = 6356.766
However it returns me
>> solve(Re.*Z/Re.+Z==.hi)(Z)
solve(Re.*Z/Re.+Z==.hi)(Z)
↑
Error: Invalid use of operator. (over the plus symbol)
Am I doing something wrong? I am a little confused this the code I looked up just says write solve, your equation = (something) (variable)
Other code help:
P2 = 101325 * exp(-B((h-h(1))/t(1)) – This was just a manual calculation I will use to see if I had written anything wrong. 
ai = [-6.5000, 0, 1.0000, 2.8013, -0.0050, -2.8000, -2.0000,0]
B =(go/Rs)
go = 9.80666
Rs = .287054
B (returns value of 34.1631) %okay no problems here
But my full equation is (to edit this question further)

syms Z
hi = [0 , 11 , 20, 32 , 47, 51 , 71 , 84.852 , 90 ];
Re = 6356.766;
for i=1:length(hi)
    A(i) = solve((Re*Z)/(Re+Z)==hi(i), Z);
    fprintf('%0.4f\n', A(i))
end
