I would like to identify the row indices of two minimum values in a cell array, containing data Zi. Searching for a single value is simple (see below) but how to I search for the minimum and the closest value to that minimum?

minimum value search:
            c=find(min(Z)==Z); %find indices

How about:
copyZ = Z;
c =find(min(Z)==Z);
copyZ(c) = NaN;
c2=find(min(copyZ)==copyZ);

or
s = unique(sort(Z));
c =find(s(1)==Z);
c2= find(s(2)==Z);

Of course if you don't need the indices separated the 2nd solution could be written as:
s = unique(sort(Z));
c =find(Z <= s(2));
