Write a function that returns the error between qhat and $q$ as defined above.

Hint: Your function should return values on the order of $1e-15$ for qhat and $9$ generated as below.

$q=$randn$(10)$

$q=\frac{q}{n}$orm$(q)$

$=$rand$()**2**$

qhat $=$exp$(im**)**q$

@show $eve{c}_e$rror $(qhat,q)$;

using LinearAlgebra: norm

function evec$\_$error$($qhat::AbstractVector, q::AbstractVector$)$

@assert isapprox$($norm$($qhat$),1\mathrm{.}0)$ "qhat is not of unit norm"

@assert isapprox$($norm$($q$),1\mathrm{.}0)"$q is not of unit norm"

alpha $=$ qhat ${?}^{\text{'}}**q$

error qhat $-??**q$

return error

end

Run
