    How to write Matlab code using fdtd method to determine MIMO capacity for indoors?

    fdtd method You should find the Electromagnetic Simulation using FDTD's book of Sullivan. It is an useful book to write FDTD's code. Cheers,

    Can I simulate the propagation of laser pulses in ionized gas using optoFDTD?

    What is optoFDTD? I'm sorry. We are talking about optiFDTD? not optoFDTD. Right?

    Can I simulate the propagation of laser pulses in ionized gas using optoFDTD?

    What is optoFDTD? optiFDTD looks great. Anyway, try to find Taflove or Sullivan FDTD books before getting started with optiFDTD. Cheers,

    Matlab: Integral Calculation Issues

    Hello everybody, I'd like to use Matlab to calculate the following expression C=∫x^4*exp(x)/(exp(x)-1)^2 dx with x[a,b]. I made the matlab code as following f=inline('x.^4*exp(x)./(exp(x)-1).^2'); C=quad(f,a,b); Could you please to tell me whether my code is right or not? Are there any...

    How can we solve the following equation

    Thanks man ! I think that approach is difficult to implement numerically. Since there are a large possible roots from your last equation. In my above equation has only one possible root. cheers, lqkhai
