can anyone help me to solve these error

% to calculate the specific volume v of n butane at 500 k and 18 atmp
function [y] = specvol(V)
Tc = 425.2; % data from Perry's Chemical Handbook critical constant
pc = 37.5; % data from Perry's Chemical Handbook { bar*1*10^5Pa/bar*1 atm/10
T = 500 ;
P = 18 ;
R = 0.082050 ;
aRK = 0.42748*(R*Tc)^2/pc ;
aRK = aRK*(Tc/T)^0.5 ;
bRK = 0.08664*(T*Tc/pc) ;
y = P*v^3- R*T*v^2 + ( aRK - P*bRK^2 - R*T*bRK)*v- aRK*bRK ;
end

function [y] = specvol(V) % change capital V to v

[madhan ravi]

Ofcourse if v is a vector then vectorize the last line by changing ^ to .^
