I am trying to create two arrays - one for time, which represents all of the x values for the graph, and one for y, which represents the corresponding y values for each time. The arrays need to be the same length. One section of the graph is a constant, and I am unable to get the y array to be the same length as x. For example, if x is [1 2 3 4 5], the problem I'm running into is that I need y to be [1 1 1 1 1] but can only set the code to be [1, 1].

Please provide the code example. It is unclear to me what your problem is with the array lengths.

I am creating a function that returns t, a time vector, and e, the corresponding y values of the plot. If plot(t,y) were to be done, it would generate a graph that contained all of the matching t and y values. The graph is given, and the portion that I am currently working on is where y=.5 for an amount of time, t. The code currently is:
tsustain = (10+1/fs):1/fs:20;
t = [t, tsustain];
e = [e, s];
Where the start value t is from a previous section. I need e to be [e s s s s s], where the total length of e will then match the length of t.

e = [e, repmat(s, 1, length(tsustain))]
