reading the value of a specific tag from fiff file in mne-matlab

Hi All, a recent joinee to this forum. I have recently started to analyze fiff files outside of the Neuromag suite, and I am using mne-matlab. Initially, I wanted to read the value of a specific tag, which I can see in the fiff file as 265 (for ex. I used show_fiff -vt in the neuromag world). The file says “3 doubles” and I wanted to know the value of this (it is the value of the origin).
I have tried fiff_read_tag and fiff_read_tag_info, but I am not clear as to how I can get the actual value of the origin coordinates ?
Thanks.
