gin(1)=[]; q(1)=[]; % eliminate duplicate q=0 case
bin = sqrt(gin.^2 + ef); % initial search vector
be = pwg(la0,ef,ec,a,bin,m,tol); % solution vector for beta
ga = sqrt(be.^2 - ef); ac = sqrt(be.^2 - ec); % gamma and alpha_c vectors
E = norm(pc*ac + ga.*tanh(ga*k0*a + j*m*pi/2)) % computational error norm
num2str([be,ga,ac],’%12.6f’) % table
pl form the table from the following program

Do you have the function pwg?
