You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: wing_verify_downwash.m
    path of file: ./repos/LADAC/aerodynamics/vlm_wing/verification
    
    the code of the file until where you have to start completion: %% Verifying the nonlinear vortex step method with fundamental solutions
% 
% Compare the induced angle of attack of the NLVSM wit
    
function alpha_i = inducedAlpha( c_L_alpha, V_Ab_inf, V_i, Gamma, l, c, local_incidence )

[alpha_inf,~] = aeroAngles(-V_Ab_inf);

alpha_inf = alpha_inf + local_incidence;

c_L_inf = 2*pi*alpha_inf;
span = sum(l(2,:));
c_F = 2*repmat(Gamma./vecnorm(V_Ab_inf,2).^2,3,1).*cross(V_Ab_inf+V_i,span*l)./repmat((vecnorm(l(2:3,:),2).*c),3,1);
c_L = -c_F(3,:);

alpha_i = (c_L-c_L_inf)./c_L_alpha;
