What form are your numbers in? A vector y? Maybe this:
logicalIndexes = y > 20 & y < 30;
firstElement = find(logicalIndexes, 1, 'first');
lastElement = find(logicalIndexes, 1, 'last');
numberOfElements = lastElement - firstElement + 1;
but it really depends on what your data is doing and what you're after. That's just one possible interpretation. Please clarify by giving an example.
