I have a table with 3 columns. COLUMN one has a serial date number. Column two has the time and column three has a value. I want to filter the table so that I got only serial date numbers in the range of 23. September 2015, 3 pm to 24. September 2015, 5 pm, 3. june 2014, 4 pm to 5. June 2014, 7 pm.
thanks for your help

datelimstr = {'23. September 2015, 3 pm', '24. September 2015, 5 pm', '3. june 2014, 4 pm', '5. June 2014, 7 pm'};
datelim = datenum(datelimstr, 'DD mmmm YYYY, HH PM');
SD = YourTable.SerialDate;
inrange = (SD >= datelim(1) & SD <= datelim(2)) | (SD >= datelim(3) & SD <= datelim(4));
SubTable = YourTable(inrange,:);
This presumes that the "serial date number" includes the time in it and not just the integer part. If not then we need to know what the format is for the time column.

I had a typo, but otherwise it should have worked, provided the date strings were in the format you posted, complete with commas and period. Anyhow, without the time information:
datelimstr = {'23. September 2015', '24. September 2015', '3. june 2014', '5. June 2014'};
datelim = datenum(datelimstr, 'DD. mmmm YYYY');
SD = YourTable.SerialDate;
inrange = (SD >= datelim(1) & SD <= datelim(2)) | (SD >= datelim(3) & SD <= datelim(4));
SubTable = YourTable(inrange,:);
