how to filter data in matlab like in excel

I have a variable 'data' with 2 columns, time (1-24) and energy consumption. I have a whole year of data. If I only wanted to look at the consumption at 10 pm, how could I filter out the energy consumption data points at 10pm?
Thanks for your help

You can use indexing. For example:
