1. A square-based pyramid has the volume V. If the vertical height is H (the normal distance from the square base to the point), write a MATLAB function that:
has V and H as input arguments
calculates the length of the side of the square (S)
has S as an output argument
Write MATLAB code that tests the function for the values:
V = 10 m3 and H = 2 m.
V = 2.586×106 m3 and H = 146.6 m (the original dimensions of the Great Pyramid of Giza).
2. Repeat SPIDER 2 Q1, but write a function that accepts a year as an input argument and determines whether that year is a leap year. The output should be the variable extra_day, which should be 1 if the year is a leap year and 0 otherwise.
You must write a script file that thoroughly tests whether your function works correctly.

The file CO2.txt, found on Blackboard with this assignment, contains 50 numbers, which represent the concentration of atmospheric carbon dioxide (parts per million) recorded at Mauna Loa, HI. The data in the file are the CO2 values on May 15th of each year from 1961 through 2010, (with background level CO2 removed). Fit an exponential model. Use the model to predict the CO2 value for May 15, 2015. Print the result to the screen using fprintf. The actual value was 125.1ppm.
