+% Generates a discrete sine wave with the following properties
+
+% A: Amplitude
+% F0: frequency
+% fs: sampling frequency
+% theta: initial phase
+% nstart: first sample index
+% nend: last sample index
+function x = gensin(A, F0, fs, theta, nstart, nend)

+% zero the column vector to the right size
+fullSeries = zeros(nend-nstart+1, 1);

+% go through all the elements until the end
+for i = 1:nend
+    % apply the sine wave for every element
+    fullSeries(i) = A*sin(2*pi*F0*i/fs + theta);
+end
