Hello, I understand the handle of function @f, my question is about the fft and ifft part.
c0 = fftshift(1i*(-n/2:1:n/2-1)');
D1 = @(f) real(ifft(c0.*fft(f)));
What will D1 return?
Thanks

I'm not sure what you want us to tell you other than a handle to an anonymous function that calculates the real part of the inverse fft of c0 multiplied by the fft of f.
As anonymous functions go, this is not a very well constructed function though, since it multiplies a fixed length vector with a variable length input. Unless f is a row vector of length n the function will error.
