MATLAB: Finding strings in a 21 x 1 cell array.

cell arrayismember

I have a cell array that looks like this:newsequence =
    'CGT'
    'GAC'
    'AGT'
    'CCT'
    'CTC'
    'CTT'
    'TAC'
    'CGA'
    'AAG'
    'GGA'
    'AGA'
    'ATA'
    'AAA'
    'GTG'
    'GCG'
    'TGA'
    'TGC'
    'ATT'
    'ACG'
    'CCT'
    'GCA'
I am interested in finding the location of 'TAC'. When I use this function: found=strfind(newsequence,'TAC'); I end up with a cell array with all zeros and a 1 in the 7th row. I want it to display a 7 because that is the location of 'TAC', but I can't seem to figure it out.

newsequence  = {'CGT'
    'GAC'
    'AGT'
    'CCT'
    'CTC'
    'CTT'
    'TAC'
    'CGA'
    'AAG'
    'GGA'
    'AGA'
    'ATA'
    'AAA'
    'GTG'
    'GCG'
    'TGA'
    'TGC'
    'ATT'
    'ACG'
    'CCT'
    'GCA'};
mask=strcmpi(newsequence ,'TAC');
rows=find(mask)
    rows =
         7
or you could combine both command in one as:
rows=find( strcmpi(newsequence ,'TAC') )
