%importing and reading text file
fid = fopen('A9P3data-S19.txt');
mat = fscanf(fid, '%f ', [3,inf]);
%assigning values for variables from file obtained
w = mat(1,1);
day = mat(2,1:13);
h = mat(3,1:13);
v = mat(1,2:14);
%calculating instantanious volumetric flow rate
Q = 0.85*v.*w.*h;
%calculating total amount of water flowed in 1 year period
V = 86400*integral(Q,1,366);
