How to compare the index of first 12 values with the next set of 12 values?

I have a structure named - (handles.GEN.kWhprice) in which the monthly price of energy is stored. I have to implement a check which compares the first 12 values with the next set of 12 values.

I.e. first 12 values are taken as a reference and the set of next 12 values (each year) are compared. If the values for each month match, then I set a flag as 1 -( set( handles.checkbox_year,'Value',1);

What should be the code for comparing such a trend?

Assuming handles.GEN.kWhprice is a structure with two fields, one for last year and one for this:

 if ~all(handles.GEN.kWhprice.lastyear - handles.GEN.kWhprice.lastyear)
    set( handles.checkbox_year,'Value',1);
 end

Note that the statement is only true if the entire array is equal, and there is no tolerance level. This means that any variation in any month will make your flag 0.
