Mirrored ifft and ifft2

So from what i gather ifft and ifft2 are meant to produce mirrored/syemetrical FIDs

Here is my one. I need to do linebroadening on it. I was wondering if there is a way for matlab to give out basically a one sided version of this. Which would look something like the following.

Origionally i tried to just remove the right hand side but after i fourier transformed it back the signal was changed.

For the signal processing i am going to do it needs to be none 'mirrored'

Any help would be greatly appreciated

If you do ifft(x,'symmetric'), the actual right hand side values will be ignored, or rather assumed to be a mirroring of the left half, e.g.,

x=ifft([0 0 0 0 0 1 2 3 4 ],'symmetric')

x = 1×9

0 0 0 0 0 0 0 0 0
