If your matrix is numerical, you can only have numbers in it, not some string like "DBLCL"

If DBLCL is a variable that has a number in it, you can do something like this:

m = rand(11,10); % Sample data.
% Find indexes matching the replacement criteria.
indexes = m > 0.2 & m < 0.9;
% Do the replacement.
m(indexes) = 99 % Or whatever other number you want.
