I need to be able to copy the values of a line from my plot. I know that the line is saved as a 1x70 vector in the workspace, but is there a function to copy these numbers to the clipboard. I ultimately want to use this function in the app designer, so saving directly from the workspace isn't ideal.

Try siomething like this —
x = 0:10;
y1 = x.^2;
y2 = 50*sin(2*pi*x/10)+50;
figure
hp = plot(x, y1, x, y2);
Line1X = hp(1).XData
Line1X = 1×11
0 1 2 3 4 5 6 7 8 9 10
Line1Y = hp(1).YData
Line1Y = 1×11
0 1 4 9 16 25 36 49 64 81 100
Line2X = hp(2).XData
Line2X = 1×11
0 1 2 3 4 5 6 7 8 9 10
Line2Y = hp(2).YData
Line2Y = 1×11

What function can I use to copy each of these values to a system clipboard to export them as a excel type array?

I doubt that there is a specific function for that. You would likely have to do something like this —
x = 0:10;
y1 = x.^2;
y2 = 50*sin(2*pi*x/10)+50;
figure
hp = plot(x, y1, x, y2);
Line1X = hp(1).XData.';
Line1Y = hp(1).YData.';
Line2X = hp(2).XData.';
Line2Y = hp(2).YData.';
T1 = table(Line1X, Line1Y, Line2X, Line2Y)
T1 = 11×4 table
Line1X Line1Y Line2X Line2Y ______ ______ ______ ______ 0 0 0 50 1 1 1 79.389 2 4 2 97.553 3 9 3 97.553 4 16 4 79.389 5 25 5 50 6 36 6 20.611 7 49 7 2.4472 8 64 8 2.4472 9 81 9 20.611 10 100 10 50
writetable(T1,'YourFileName.xlsx')
