Hai Matlab Users , specifically stats toolbox experts.

Here is my problem. A general statistics problem, which might be solved by matlab.

I have 5 measurements of the deviation ( from a baseline) of a  temperature at 5 times of the day each day. I have made measurements for 50 days. So 5 * 50 measurements. 

Now I need to compare these deviations for all the days and see if there is a "pattern" repeating accross number of days. I have been thinking of using slopes (calculated using five measurements per day) and then compare the slopes. What test can achieve this in matlab ?Is there a better way of comparing the means or slopes knowing that they have been computed from five sample points only ?

Thank you
