How to understand the symbolic inverse fourier transform result?

Dear all,

I need to perform a symbolic inverse fourier transformate. I tried the following

syms alpha lambda n  positive %alpha, lambda and n are real positive variables

syms w vc real %w and vc are real variables

PSD = (alpha/(alpha+1)*dirac(w)+1/(alpha+1)*n*sin(pi/n)/(2*pi*vc)*1/(1+(abs(w)/vc)^n))

ifourier(PSD)

and I got as result

(alpha/(alpha + 1) + (n*sin(pi/n)*(fourier(heaviside(w)/((w/vc)^n + 1), w, -x) + fourier(heaviside(-w)/((-w/vc)^n + 1), w, -x)))/(2*vc*pi*(alpha + 1)))/(2*pi)

but I am not able to understand the part

fourier(heaviside(w)/((w/vc)^n + 1), w, -x)

what does it mean?

Many thanks

Hi Fast Car,

This issue of working with ifourier has been brought to the notice of developers. They may investigate the matter further.
