To analyze global temperature and carbon dioxide measurements for seasonal, annual and longer term trends b parsing and loading complex data ?les and dealing with missing data, writing functions to decide whether long-term trends in the data can be detected, outputting nicely formatted results and ?gures summarizing your analyses.

This assignment makes use of functions. We will learn about these in week 8. However it is possible to start on the assignment by writing your code in one script and moving segments of it to functions later. e.g., you can load and plot the data using a script as we have done so far in the course.

For this assignment you will write four functions and a main script as follows:  assign1.m - main script that calls the functions below and makes the four ?gures requested,  getco2.m - function to read in CO2 data and create a structure containing these data (see Section 5 below), gettemp.m - function to create a structure to hold temperature data,  getstats.m - returns running mean and some other statistics.
