Explanation / Answer

%% Clear the command line, clear all workspace variable

clc; clrscr;

%% Import sample weather

function data wd = xlsread('weather_data.xls');

% read in the data to wd using xlsread wd = wd';

% transpose wd, so that months are in columns month = 2

% set the month of January

%% Average in a month

month_values = wd(:,month)

month_values(month_values<0)=[] ;

average_in_a_month = mean(month_values) ;

%% Max in a month

max_in_a_month = max(wd(:,month)) ;

%% days of month when zero inches fell

days_when_zero = find(month_values==0) ;

%% # of days zero inches fell %

num_days_when_zero = numel(days_when_zero)

num_days_when_zero = sum(month_values==0)

%% days when some rain fell

num_days_when_zero = numel(days_when_zero)

%% average inches of only days in which some rain fell
