采纳的回答： Paolo

I have a cell array a = {'abc__first__element' ; 'def__second__element'; ghi__third__element'}

I want to extract the string after first '__'

My final answer should be a = {'first__element'; 'second__element'; 'third__element'}

How can do this?

Thanks a lot

+1 nice and simple. To avoided nested cell arrays in the output use the 'once' option:

regexp(a,'(?<=__)(.*)','match','once')
