I have a martrix with year, month, and two variables. With 7 years worth of data.
year month air temp humidity
2007 10 254.2 446.3
I am trying to subset certain months, 10,11,12,1,2,3. I want the data included in the entire row.
Any idea on how i could do this?
Cheers.

Use ismember.
idx = ismember(T.month, [10,11,12,1,2,3]);
T(idx,:)

Monthly_airtemp = data name
idx = ismember(monthly_airtemp, [10,11,12,1,2,3]);
monthly_airtemp(idx,:)

I assumed your example below was a table
year month air temp humidity
2007 10 254.2 446.3
If monthly_airtemp is a vector of integers representing months, then your code above should work.
