% ket Transforms a vector into normalized column vector.
function w=ket(;5)
[y,x]=size(v);
if x>1,
w=v.';
else
w=v;
end % if
% normalisation
w=w/sqrt(w'*w);

function Q = bra_ket(Psi,Phi,f_op)
Q = integral3(@(r1,r2,r3) Psi(r1,r2,r3).*f_op(Phi(r1,r2,r3)),r1min,r1max,r2min,r2max,r3min,r3max)
end
(3)
function Q = bra_ket_traps(Psi,Phi,f_op,r1,r2,r3)
opPhi = f_op(Phi,r1,r2,r3); % Here you might need additional argument
Q = trapz(r3(1,1,:),trapz(r2(1,:,1),trapz(r1(:,:,1),conj(Psi).*(opPhi)),2),3);

% cohstate cohstate(alpha,M) gives the state vector of M elements for
% a coherent state with given alpha
function v=cohstate(alpha,M)
v=zeros(M,1);
v((0)+1)=1;
for n=0:M-2
v((n+1)+1)=alpha/sqrt(n+1)*v((n)+1);
end % for
v=v/sqrt(v'*v);

Invalid syntax:
function w=ket(;5)
Inside the parentheses in a function definition should be a list of variable names. ";5" is not a list of variable names.
Maybe you meant:
function w=ket(v)

If you are using the option on the green Run button to have it prompt you for the parameter values then OK, go ahead and do that. Personally I find doing that to be slow and not to offer me fine enough control for my purposes, but if that is what you want to do, go ahead and get back to us if you encounter further errors in your code.
Personally I use the techniques I described earlier https://www.mathworks.com/matlabcentral/answers/1909685-what-is-the-error-example#comment_2608885
