Consider two arrays A & B:
A={'blah_12_blah' 'blah_456_blah' 'blah_789_blah' 'blah_NPQZ_blah'}
B={'blah_NPQZ_blah' 'blah_135_blah' 'blah_579_blah' 'blah_12_blah' 'blah_RSTX_blah'}
The termn 'blah' basically refers to any string that comes before and after the parts of interest and each 'blah' could be a different string.
I would like to compare these two arrays and fine only the members that have the "part of interest" in common. In this case it means that after comparing A & B, only the elements 'blah_12_blah' and 'blah_NPQZ_blah' will show up as output, since these elements have the parts '12' and 'NPQZ' incommon, no matter what their respective 'blah' parts are.

A={'blah_12_blah' 'blah_456_blah' 'blah_789_blah' 'blah_NPQZ_blah'}
A = 1×4 cell array
{'blah_12_blah'} {'blah_456_blah'} {'blah_789_blah'} {'blah_NPQZ_blah'}
B={'blah_NPQZ_blah' 'blah_135_blah' 'blah_579_blah' 'blah_12_blah' 'blah_RSTX_blah'}
B = 1×5 cell array
{'blah_NPQZ_blah'} {'blah_135_blah'} {'blah_579_blah'} {'blah_12_blah'} {'blah_RSTX_blah'}
A_partofinterest = extractBetween(A,'_','_')
A_partofinterest = 1×4 cell array
{'12'} {'456'} {'789'} {'NPQZ'}
B_partofinterest = extractBetween(B,'_','_')
B_partofinterest = 1×5 cell array
{'NPQZ'} {'135'} {'579'} {'12'} {'RSTX'}
A_new = A(ismember(A_partofinterest,B_partofinterest))
A_new = 1×2 cell array
{'blah_12_blah'} {'blah_NPQZ_blah'}
B_new = B(ismember(B_partofinterest,A_partofinterest))
B_new = 1×2 cell array
{'blah_NPQZ_blah'} {'blah_12_blah'}

A={'123abc' '456klm' '1a2b3c'}
A = 1×3 cell array
{'123abc'} {'456klm'} {'1a2b3c'}
B={'blah123abcblah' 'blah789ijkblah' 'blah11aa22bbblah' '123abc' '456pqr' '1a2b3c'}
B = 1×6 cell array
{'blah123abcblah'} {'blah789ijkblah'} {'blah11aa22bbblah'} {'123abc'} {'456pqr'} {'1a2b3c'}
contains(B,A)
ans = 1×6 logical array
1 0 0 1 0 1
B(contains(B,A))
ans = 1×3 cell array
{'blah123abcblah'} {'123abc'} {'1a2b3c'}
