discrete Fourier transform Guys,I do get the same result on my machine,but I think this Fourier analysis doesn't make sense,at least my supervisor says so.he says I have to tell the program that my function is periodic,so that the Fourier transform of it should go to zero for t infinity. |

Integro-differential equation @Leoinid:I tried to remove the 2nd derivative under the integral,but because the kernel is a 2nd type modified Bessel function it would lead to a divergent 2nd derivative of kernel which make it worse,so I think that I have to deal with this equation the way it is and solve it by discretization if possible.any idea how to discretize? |

Integro-differential equation Guys,first of all I should say that K(x,u) is first modified Bessel function and u is just a variable under the Integral.secondly I haven't tried your answers so far but I think Leonid's is understandable.@ Leonid:Does any solver exist in mathematica for this? |

integro differential equation Guys,my integral limits are from -infinity to infinity and yes the D is partial derivative.y is a function of x,t. |
