hi, i would need some info on how can implement in MATLAB or FORTRAN (g90) the Numerical evaluation of the integral
[tex] \int_{-\infty}^{\infty}dxf(x)exp(iux) [/tex]
and the evaluation of the ivnerse Fourier transform
[tex] \int_{-\infty}^{\infty}du\frac{F(u))}{\int_{-\infty}^{\infty}g(x)exp(iux)dx} [/tex]
the idea is to implement some numerical tool to evaluate Fourier transform integral, in order to apply them to solve Wiener-Hopf equation.
