Could you help me with this? tried to plot, but error comes out. messed up with vector and syms?
zR=0.0201; z0=1.0264; tau=0.5; nu0=2.606; Lw=1.0810; lambda=2.68*10^-6; c=3*10^8; k0=2*pi/lambda; omega=2*pi*c/lambda; xi =@(t,xi0) xi0+nu0.*tau-exp(t)/nu0.^2*(cos(xi0+nu0*tau)-cos(xi0)+nu0.*tau.*sin(xi0)); zeta= @(t,xi0) xi/(zR*k0); f = @(xi0,x0,t) exp(x0.^2/(1+zeta(t,xi0).^2)-i*(zeta(t,xi0).*x0.^2/(1+zeta(t,xi0).^2)-atan((zeta(t,xi0)))+7*(xi(t,xi0)))); xT = @(T) T; T=linspace(0,1); t= xT(T); F= zeros(size(T)); for K = 1 : length(T) F(K) = abs(integral2(@(xi0,x0) f(t(K), xi0, x0), -3*k0*zR, 3*k0*zR, -1, 1)); end plot(t, F)
