hello people.i would like some help with a problem i have in matlab.does anyone know how to integrate and plot the following function
y=besselj(1,omeg.*x).*cos(omeg.*x)./(besselj(1,omeg.*x)+1i.*Y1).*besselj(0,omeg.*x)-(1./k).*(besselj(0,omeg.*x)+1i.*YO).*besselj(1,omeg.*x);

Integrate with what limits and with respect to which variable?

When I substitute in fixed values for omeg, k, YO and Y1, y becomes complex and oscillating in both real and imaginary, so the integral from x = -infinity to +infinity would be 0 + 0i. But over any subset of reals, there would be a lot of real and complex cancellation to work through and the integral would be complex except over very specific x range choices.
It appears to me that if the integral is over x, that you are not going to be able to remove the multiple besselj, except by identity transformations that leave you no further ahead (e.g., transforming to calls to the Huen function.)
