Transforming a complex single sided spectra to time domain

I want to transform a single sided complex spectrum to a time domain wave using the IFFT function. I want a real time domain signal so build a 2 sided conjugate symmetrical signal but the output of my IFFT is still complex. Can someone please advice where I am going wrong? Code below (FreqData is the complex single sided spectrum)

H=flipud(conj(FreqData))

ifft([FreqData;H])

Hi there,

Here is a link to an easy-to-use function to perform fft or ifft along with an example:
