How can I make IFFT function return me a function instead an array

y = 1./fft(x);
h = ifft(y);
I was trying to do an inverse fft. Matlab returns me an array. How can I get a function instead of array when using ifft?

Hello Siwei, could you provide information on what x and y look like?

You cannot do that with fft and ifft. However you can use the continuous transforms. https://www.mathworks.com/help/symbolic/fourier.html
syms x
y = fourier(x);
h = ifourier(y);
