I imported a set of data into matlab and have plotted the curve. However, I do not know how to use trapz to find the area under the curve.

I did not open your text file, but assuming you got that plot using
plot(x,y)
then it should be as easy as
trapz(x,y)

% Load data
data = readtable('discharge 30mA.txt');
% Drop the last point, which is NaN
x = data{1:end-1,1};
y = data{1:end-1,2};
% Plot the data
figure
plot(x,y)
% Calculate the area
area = trapz(x,y)
