Answer 1

[KALYAN ACHARJYA]

ifourier Have you looked here ?

[Somdyuti Das Adhikary]

I tried using piecewise to define the function. But then, I am not able to use either ifourier or ifft to find the inverse Fourier Transform

[Walter Roberson]

piecewise() is part of the Symbolic Toolbox, which uses fourier() and ifourier()

However, ifourier() is unable to handle this particular case if you write it in piecewise(). It can, however, handle if if you write the expression in terms of heaviside() -- but you do have to be careful about the boundary conditions: check out sympref('heavisideatorigin')
