Hi, I would like to know if there is a way to integrate a multiplication of 2 symbolic functions with respect to a single variable. For example:
mu_0 = 4.*pi.*1e-7;
ep_0 = 8.854e-12;
mu_r = 1;
ep_r = 1;
mu=mu_0*mu_r;
ep=ep_0*ep_r;
f = 0.159e9;
omega = 2.*pi.*f;
sig1=0;
sig3=10;
gamma0=@(x) sqrt(x.^2-omega^2*mu*ep+1i*omega*mu*sig1);
gamma3=@(x) sqrt(x.^2-omega^2*mu*ep+1i*omega*mu*sig3);
F_A_Z=@(x) gamma0*gamma3;
A_Z=mu*integral(F_A_Z,0,Inf,'RelTol',1e-6,'AbsTol',1e-12,'ArrayValued',true);
Then Matlab said Undefined operator '*' for input arguments of type 'function_handle'. Could you pleas help?
Thanks

F_A_Z=@(x) gamma0(x).*gamma3(x);
