Hi anyone
I'm designing a coupled line directional coupler. In the design procedure, I have two nonlinear equations to be solved. I tried to solve this equations with 'solve' function in matlab, but the given answers are not true. I also used the 'ezplot' function to solve the equations, but it shows numerous intersections between two plot of equations. the answers given by 'sovle' function are approximately -220 and 96, but the true answers are approximately 0.02 and 0.06 ! the equations are attached. plz help!
